SUBJECT TO COMPLETION, DATED SEPTEMBER 6, 2019

Senseonics Holdings, Inc.

$82,000,000
5.25% Convertible Senior Notes due 2025, Guarantees of
5.25% Convertible Senior Notes due 2025 and any
Shares of Common Stock Issuable upon Conversion

On July 25, 2019, we sold $82.0 million aggregate principal amount of our 5.25% Convertible Senior Notes due 2025 (the "notes"). We sold the notes in a transaction exempt from the registration requirements of the Securities Act of 1933, as amended (the "Securities Act"). This prospectus may be used from time to time by certain recipients of the notes (as further provided for in the section entitled "Selling Securityholders" in this prospectus, the "selling securityholders") to offer up to $82.0 million in aggregate principal amount of the notes, the subsidiary guarantees and the shares of our common stock, par value $0.001 per share ("common stock") issuable upon conversion of the notes, in any manner described under the section entitled "Plan of Distribution" in this prospectus. The selling securityholders may sell the notes or any such shares of common stock in one or more transactions at fixed prices, at prevailing market prices at the time of sale, at prices related to such prevailing market prices, at varying prices determined at the time of sale or at privately negotiated prices directly to purchasers or through underwriters, broker-dealers or agents, who may receive compensation in the form of discounts, concessions or commissions. If the selling securityholders use underwriters, broker-dealers or agents, we will name them and describe their compensation in a supplement to this prospectus as may be required. We will receive no proceeds from any sale by the selling securityholders of the securities offered by this prospectus, but in some cases we have agreed to pay certain registration expenses. Please read this prospectus and any applicable prospectus supplement carefully before you invest.

The notes are not listed on any securities exchange. Our common stock is listed on the NYSE American and trades under the symbol "SENS." On September 5, 2019, the closing sale price of our common stock on the NYSE American was $1.06 per share.

We are an emerging growth company as that term is used in the Jumpstart Our Business Startups Act of 2012 (the "JOBS Act") and a smaller reporting company as defined in Rule 12b-2 promulgated under the Securities Exchange Act of 1934, as amended (the "Exchange Act"). As such, we have elected to rely on certain reduced public company disclosure requirements. See "Implications of Being an Emerging Growth Company and a Smaller Reporting Company."

Investing in our securities involves risks. You should carefully read and consider the risk factors included in our periodic reports, in any applicable prospectus supplement relating to a specific offering of securities and in any other documents we file with the Securities and Exchange Commission ("SEC"). See the sections entitled "Risk Factors" below on page 14, in the documents incorporated by reference in this prospectus and in the applicable prospectus supplement, if any.

Neither the SEC nor any state securities commission has approved or disapproved of these securities, or determined if this prospectus is truthful or complete. Any representation to the contrary is a criminal offense.

The date of this prospectus is                    , 2019.

RISK FACTORS

Investing in our securities involves risks. You should carefully consider the risk factors described below and in Part I, Item 1A, "Risk Factors" in ourAnnual Report on Form 10-K for the fiscal year ended December 31, 2018 and in Part II, Item 1A, "Risk Factors" on ourQuarterly Report on Form 10-Q for the quarter ended June 30, 2019, and any updates to those risk factors or new risk factors contained in our subsequent Quarterly Reports on Form 10-Q, all of which is incorporated by reference into this prospectus, as the same may be amended, supplemented or superseded from time to time by our filings under the Exchange Act, as well as any prospectus supplement relating to a specific offering or resale. Before making any investment decision, you should carefully consider these risks as well as other information we include or incorporate by reference in this prospectus or in any applicable prospectus supplement or free writing prospectus. For more information, see the sections entitled "Where You Can Find More Information" and "Incorporation by Reference" above. These risks could materially affect our business, results of operations or financial condition and affect the value of our securities. You could lose all or part of your investment. Additionally, the risks and uncertainties discussed in this prospectus or in any document incorporated by reference into this prospectus are not the only risks and uncertainties that we face, and additional risks and uncertainties not presently known to us or that we currently deem immaterial may also affect our business, results of operations or financial condition.

Risks Related to the Notes

The notes and the subsidiary guarantees are effectively subordinated to our secured debt and the secured debt of our subsidiary guarantors, as applicable, and the notes are structurally subordinated to any liabilities of our non-guarantor subsidiaries.

The notes rank senior in right of payment to all of our existing and future indebtedness that is expressly subordinated in right of payment to the notes; rank equal in right of payment with all of our existing and future unsecured, senior indebtedness, including the 2023 notes (except that, with respect to the subsidiary guarantees, the notes rank senior in right of payment to the 2023 notes); rank structurally junior in right of payment to all the liabilities, including trade payables, of any of our subsidiaries that are not subsidiary guarantors; and are effectively subordinated to all of our existing and future secured indebtedness to the extent of the value of the assets or property securing such indebtedness. The subsidiary guarantors, jointly and severally, fully and unconditionally guarantee our payment obligations under the notes. The subsidiary guarantees rank senior in right of payment to all of the existing and future liabilities that are expressly subordinated in right of payment to the subsidiary guarantees; rank equal in right of payment with all of the existing and future unsecured, senior indebtedness of each subsidiary guarantor; and are effectively subordinated to all of existing and future secured indebtedness of each subsidiary guarantor to the extent of the value of the assets or property securing such indebtedness. In the event of our bankruptcy, liquidation, reorganization or other winding up, our assets will be available to pay obligations on the notes only after all secured indebtedness, including the Loan and Security Agreement, dated as of July 16, 2019, among Solar Capital Ltd., as collateral agent and lender, the Company and Senseonics, Incorporated, as borrowers (the "credit agreement"), have been repaid in full from the assets securing such indebtedness. There may not be sufficient assets remaining to pay amounts due on any or all of the notes then outstanding.

You will not have any claim as a creditor against any of our future subsidiaries that do not become subsidiary guarantors. Those non-guarantor subsidiaries are separate and distinct legal entities and will have no obligation, contingent or otherwise, to pay any amounts due under the notes, or to make any funds available therefor, whether by dividends, loans, distributions or other payments. Indebtedness and other liabilities, including trade payables, whether secured or unsecured, of those subsidiaries are structurally senior to your claims against those subsidiaries.

Table of Contents

In the event of a bankruptcy, liquidation, reorganization or other winding up of any of our non-guarantor subsidiaries, those non-guarantor subsidiaries will pay the holders of their debts, holders of preferred equity interests and their trade creditors before they will be able to distribute any of their assets to us (except to the extent we have a claim as a creditor of such non-guarantor subsidiary). Any right that we or the subsidiary guarantors have to receive any assets of any of the non-guarantor subsidiaries upon the bankruptcy, liquidation, reorganization or other winding up of those subsidiaries, and the consequent rights of holders of notes to realize proceeds from the sale of any of those subsidiaries' assets, are structurally subordinated to the claims of those subsidiaries' creditors, including trade creditors and holders of preferred equity interests of those subsidiaries.

As of July 31, 2019, the principal amount of our total consolidated indebtedness was $142.7 million, of which $45.0 million was senior secured indebtedness of us and our sole subsidiary and subsidiary guarantor under the Solar Term Loan and $97.7 million was our senior unsecured indebtedness under the notes and the 2023 notes. Our sole subsidiary guarantor had $127.0 million in principal amount of indebtedness as of July 31, 2019.

Recent and future regulatory actions and other events may adversely affect the trading price and liquidity of the notes.

We expect that many investors in, and potential purchasers of, the notes will employ, or seek to employ, a convertible arbitrage strategy with respect to the notes. Investors would typically implement such a strategy by selling short the common stock underlying the notes and dynamically adjusting their short position while continuing to hold the notes. Investors may also implement this type of strategy by entering into swaps on our common stock in lieu of or in addition to short selling the common stock.

The SEC and other regulatory and self-regulatory authorities have implemented various rules and taken certain actions, and may in the future adopt additional rules and take other actions, that may impact those engaging in short selling activity involving equity securities (including our common stock). Such rules and actions include Rule 201 of SEC Regulation SHO, the adoption by the Financial Industry Regulatory Authority, Inc. and the national securities exchanges of a "Limit Up-Limit Down" program, the imposition of market-wide circuit breakers that halt trading of securities for certain periods following specific market declines, and the implementation of certain regulatory reforms required by the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010. Any governmental or regulatory action that restricts the ability of investors in, or potential purchasers of, the notes to effect short sales of our common stock, borrow our common stock or enter into swaps on our common stock could adversely affect the trading price and the liquidity of the notes.

Volatility in the market price and trading volume of our common stock could adversely impact the trading price of the notes.

The stock market in recent years has experienced significant price and volume fluctuations that have often been unrelated to the operating performance of companies. The market price of our common stock could fluctuate significantly for many reasons, including in response to the risks described in this prospectus or the documents incorporated by reference in this prospectus, or for reasons unrelated to our operations, such as reports by industry analysts, investor perceptions or negative announcements by our customers, competitors or suppliers regarding their own performance, as well as industry conditions and general financial, economic and political instability. A decrease in the market price of our common stock would likely adversely impact the trading price of the notes. The market price of our common stock could also be affected by possible sales of our common stock by investors who view the notes as a more attractive means of equity participation in us and by hedging or arbitrage trading activity that we expect to develop involving our common stock. This trading activity could, in turn, affect the trading price of the notes.

Table of Contents

We may not have the ability to raise the funds necessary to repurchase the notes upon a fundamental change, and our existing or future debt may contain limitations on our ability to repurchase of the notes.

Holders of the notes have the right to require us to repurchase their notes upon the occurrence of a fundamental change at a fundamental change repurchase price equal to 100% of the principal amount of the notes to be repurchased, plus accrued and unpaid interest, if any, as described under "Description of Notes — Fundamental Change Permits Holders to Require Us to Repurchase Notes." However, we may not have enough available cash or be able to obtain financing at the time we are required to make repurchases of notes surrendered therefor. In addition, we will be required to offer to repurchase the notes with excess proceeds from certain asset sales. Our ability to repurchase the notes may be limited by law, by regulatory authority or by agreements governing our indebtedness that exist at the time of the repurchase. The credit agreement restricts us from repurchasing the notes. Our failure to repurchase notes at a time when the repurchase is required by the indenture would constitute a default under the indenture. The occurrence of a fundamental change could cause an event of default under, or be prohibited or limited by, the terms of existing or future senior debt. If the repayment of the related indebtedness were to be accelerated after any applicable notice or grace periods, we may not have sufficient funds to repay the indebtedness and repurchase the notes.

The credit agreement prohibits us from making any cash payments to repurchase the notes.

The credit agreement prohibits us from making any cash payments to repurchase the notes upon a fundamental change. See "Description of Certain Other Indebtedness — Credit Agreement." Any new credit facility that we may enter into may have similar restrictions. Our failure to repurchase the notes as required under the terms of the notes would constitute a default under the indenture and permit holders of the notes to accelerate our obligations under the notes. A default under the indenture or the fundamental change itself could also lead to a default under the credit agreement or agreements governing our future indebtedness. If the repayment of the related indebtedness were to be accelerated after any applicable notice or grace periods, we may not have sufficient funds to repay the indebtedness and repurchase the notes.

Sales of our common stock in the public market or the perception that such sales could occur, could lower the market price for our common stock and adversely impact the trading price of the notes.

In the future, we may sell additional shares of our common stock to raise capital. In addition, a substantial number of shares of our common stock is reserved for issuance upon the exercise of stock options and upon conversion of the notes. We cannot predict the size of future issuances or the effect, if any, that they may have on the market price for our common stock. The issuance and sale of substantial amounts of common stock, or the perception that such issuances and sales may occur, could adversely affect the trading price of the notes and the market price of our common stock and impair our ability to raise capital through the sale of additional equity securities.

Holders of notes are not entitled to any rights with respect to our common stock, but they are subject to all changes made with respect to them.

Holders of notes are not entitled to any rights with respect to our common stock (including, without limitation, voting rights and rights to receive any dividends or other distributions on our common stock) prior to the conversion date with respect to any notes they surrender for conversion, but they are subject to all changes affecting our common stock. For example, if an amendment is proposed to our certificate of incorporation or bylaws requiring stockholder approval and the record date for determining the stockholders of record entitled to vote on the amendment occurs prior to the conversion date with respect to any notes surrendered for conversion, then the holder surrendering such notes will not be entitled to vote on the amendment, although such holder will nevertheless be subject to any changes affecting our common stock.

Table of Contents

Guarantees of the notes may be released.

The notes are guaranteed by Senseonics, Incorporated, our sole subsidiary as of the date of this prospectus, and each of our restricted subsidiaries formed or acquired after the date of the initial issuance of the notes that is not an excluded subsidiary. Under the terms of the indenture governing the notes, a guarantee of the notes made by a subsidiary guarantor will be released without any action on the part of the trustee or any holder of notes under certain circumstances described in "Description of Notes — Covenants — Subsidiary Guarantees."

Federal and state statutes allow courts, under specific circumstances, to void notes and subsidiary guarantees and require noteholders to return payments received.

The issuance of the notes and the related subsidiary guarantees may be subject to review under federal and state fraudulent transfer and conveyance statutes. While the relevant laws may vary from state to state, under such laws the payment of consideration will be a fraudulent conveyance if (1) the consideration was paid with the intent of hindering, delaying or defrauding creditors or (2) we or any of the subsidiary guarantors, as applicable, received less than reasonably equivalent value or fair consideration in return for issuing either the notes or a subsidiary guarantee and, in the case of (2) only, one of the following is also true:

§

we or any of the subsidiary guarantors were insolvent or rendered insolvent by reason of the incurrence of the indebtedness;



§

payment of the consideration left us or any of the subsidiary guarantors with an unreasonably small amount of capital to carry on the business; or



§

we or any of the subsidiary guarantors intended to, or believed that such entity would, incur debts beyond its ability to pay as they mature.

If a court were to find that the issuance of the notes or a subsidiary guarantee was a fraudulent conveyance, the court could void the payment obligations under the notes or such subsidiary guarantee or subordinate the notes or such subsidiary guarantee to presently existing and future indebtedness of us or such subsidiary guarantor, or require the holders of the notes to repay any amounts received with respect to the notes or such subsidiary guarantee. In the event of a finding that a fraudulent conveyance occurred, you may not receive any repayment on the notes.

The measures of insolvency for purposes of these fraudulent transfer laws will vary depending upon the law applied in any proceeding to determine whether a fraudulent transfer has occurred. In general, however, a court would consider an issuer or a guarantor insolvent if:

§

the sum of its debts, including contingent and unliquidated liabilities, was greater than the fair saleable value of all of its assets;



§

the present fair saleable value of its assets was less than the amount that would be required to pay its probable liability on its existing debts, including contingent liabilities, as they become absolute and mature; or



§

it could not pay its debts as they became due.

We cannot be certain as to the standards a court would use to determine whether or not we or any subsidiary guarantor was solvent at the relevant time, or regardless of the standard that a court uses, that the issuance of the notes and the subsidiary guarantees would not be subordinated to our or any subsidiary guarantor's other debt.

If the subsidiary guarantees were legally challenged, any subsidiary guarantee could also be subject to the claim that, since the subsidiary guarantee was incurred for our benefit, and only indirectly for the benefit of the subsidiary guarantor, the obligations of the applicable subsidiary guarantor were incurred for less than fair consideration. A court could thus void the obligations under the subsidiary guarantees, subordinate

Table of Contents

them to the applicable subsidiary guarantor's other debt or take other action detrimental to the holders of the notes.

Each subsidiary guarantee contains a provision intended to limit the subsidiary guarantor's liability to the maximum amount that it could incur without causing the incurrence of obligations under its subsidiary guarantee to be a fraudulent transfer. This provision may not be effective to protect the subsidiary guarantees from being voided under fraudulent transfer law, or may reduce or eliminate the guarantor's obligation to an amount that effectively makes the subsidiary guarantee worthless.

The increase in the conversion rate for notes converted in connection with a make-whole fundamental change or during a redemption period may not adequately compensate you for any lost value of your notes as a result of such transaction.

If a make-whole fundamental change occurs prior to the maturity date or upon our issuance of a notice of redemption, under certain circumstances, we will increase the conversion rate by a number of additional shares of our common stock for notes converted in connection with such make-whole fundamental change or during the redemption period, as applicable. The increase in the conversion rate will be determined based on the date on which the specified corporate transaction becomes effective or the redemption notice date, as applicable, and the price paid (or deemed to be paid) per share of our common stock in such transaction or on such redemption notice date, as described below under "Description of Notes — Conversion Rights — Increase in Conversion Rate Upon Conversion upon a Make-Whole Fundamental Change or during a Redemption Period." The increase in the conversion rate for notes converted in connection with a make-whole fundamental change or during a redemption period may not adequately compensate you for any lost value of your notes as a result of such transaction or notice of redemption. In addition, if the price of our common stock in the transaction is greater than $20.00 per share or less than $1.10 per share (in each case, subject to adjustment), no additional shares will be added to the conversion rate. Moreover, in no event will the conversion rate per $1,000 principal amount of notes as a result of this adjustment exceed 909.0909 shares of common stock in the event of a make-whole fundamental change or conversion during a redemption period, subject to adjustment in the same manner as the conversion rate as set forth under "Description of Notes — Conversion Rights — Conversion Rate Adjustments."

Our obligation to increase the conversion rate for notes converted in connection with a make-whole fundamental change or during a redemption period could be considered a penalty, in which case the enforceability thereof would be subject to general principles of reasonableness and equitable remedies.

The conversion rate of the notes may not be adjusted for all dilutive events.

The conversion rate of the notes is subject to adjustment for certain events, including, but not limited to, the issuance of certain stock dividends on our common stock, the issuance of certain rights or warrants, subdivisions, combinations, distributions of capital stock, indebtedness, or assets, cash dividends and certain issuer tender or exchange offers as described under "Description of Notes — Conversion Rights — Conversion Rate Adjustments." However, the conversion rate will not be adjusted for other events, such as a third-party tender or exchange offer or an issuance of common stock for cash, that may adversely affect the trading price of the notes or our common stock. An event that adversely affects the value of the notes may occur, and that event may not result in an adjustment to the conversion rate.

Some significant restructuring transactions may not constitute a fundamental change, in which case we would not be obligated to offer to repurchase the notes.

Upon the occurrence of a fundamental change, you have the right to require us to repurchase your notes. However, the fundamental change provisions will not afford protection to holders of notes in the event of other transactions that could adversely affect the notes. For example, transactions such as leveraged recapitalizations, refinancings, restructurings, or acquisitions initiated by us may not constitute a fundamental change requiring us to repurchase the notes. In the event of any such transaction, the holders

Table of Contents

would not have the right to require us to repurchase the notes, even though each of these transactions could increase the amount of our indebtedness, or otherwise adversely affect our capital structure or any credit ratings, thereby adversely affecting the holders of notes.

We cannot assure you that an active trading market will develop for the notes.

We do not intend to apply to list the notes on any securities exchange or to arrange for quotation on any automated dealer quotation system. In addition, the liquidity of the trading market in the notes, and the market price quoted for the notes, may be adversely affected by changes in the overall market for this type of security and by changes in our financial performance or prospects or in the prospects for companies in our industry generally. As a result, we cannot assure you that an active trading market will develop for the notes. If an active trading market does not develop or is not maintained, the market price and liquidity of the notes may be adversely affected. In that case you may not be able to sell your notes at a particular time or you may not be able to sell your notes at a favorable price.

Any adverse rating of the notes may cause their trading price to fall.

We do not intend to seek a rating on the notes. However, if a rating service were to rate the notes and if such rating service were to lower its rating on the notes below the rating initially assigned to the notes or otherwise announces its intention to put the notes on credit watch, the trading price of the notes could decline.

You may be subject to tax if we make or fail to make certain adjustments to the conversion rate of the notes even though you do not receive a corresponding cash distribution.

The conversion rate of the notes is subject to adjustment in certain circumstances, including the payment of cash dividends. If the conversion rate is adjusted as a result of a cash dividend paid to our common stockholders, you may be deemed to have received a dividend subject to U.S. federal income tax without the receipt of any cash. In addition, a failure to adjust (or to adjust adequately) the conversion rate after an event that increases your proportionate interest in us could be treated as a deemed taxable dividend to you. If a make-whole fundamental change occurs prior to the maturity date or upon our issuance of a notice of redemption, under some circumstances, we will increase the conversion rate for notes converted in connection with such make-whole fundamental change or notice of redemption. Such increase may also be treated as a distribution subject to U.S. federal income tax as a dividend. See "Certain Material U.S. Federal Income Tax Considerations." If you are a non-U.S. holder (as defined in "Certain Material U.S. Federal Income Tax Considerations"), any deemed dividend would be subject to U.S. federal withholding tax at a 30% rate, or such lower rate as may be specified by an applicable treaty, and if you are a U.S. holder (as defined in "Certain Material U.S. Federal Income Tax Considerations"), any deemed dividend may be subject to federal backup withholding tax at a 24% rate, which, in each case, may be withheld from subsequent payments on the notes or other amounts received by you. See "Certain Material U.S. Federal Income Tax Considerations."

The comprehensive tax reform bill could adversely affect our business and financial condition.

On December 22, 2017, President Trump signed into law new tax legislation, the Tax Act, that significantly changes the Internal Revenue Code of 1986, as amended. The Tax Act, among other things, contains significant changes to corporate taxation, including reduction of the corporate tax rate from a top marginal rate of 35% to a flat rate of 21%, limitation of the tax deduction for interest expense to 30% of adjusted earnings (except for certain small businesses), limitation of the deduction for net operating losses to 80% of current year taxable income and elimination of net operating loss carrybacks, one time taxation of offshore earnings at reduced rates regardless of whether they are repatriated, immediate deductions for certain new investments instead of deductions for depreciation expense over time, and modifying or repealing many business deductions and credits. Our federal net operating loss carryovers created in 2018 and thereafter will be carried forward indefinitely pursuant to the Tax Act. We continue to examine the

Table of Contents

impact this tax legislation may have on our business. Notwithstanding the reduction in the corporate income tax rate, the overall impact of the Tax Act is uncertain and our business and financial condition could be adversely affected. The impact of this Tax Act on holders of our notes or common stock is also uncertain and could be adverse. This prospectus does not discuss any such tax legislation or the manner in which it might affect us or purchasers of our notes or holders of our common stock. We urge purchasers of notes in this offering to consult with their legal and tax advisors with respect to such legislation and the potential tax consequences of investing in our notes and common stock.

For as long as the notes are held in book-entry form, holders must rely on DTC's procedures to receive communications relating to the notes and exercise their rights and remedies.

We issued the notes in the form of one or more global notes registered in the name of Cede & Co., as nominee of DTC. Beneficial interests in global notes are shown on, and transfers of global notes are effected only through, the records maintained by DTC. Except in limited circumstances, we will not issue certificated notes. See "Description of Notes — Book-Entry, Settlement and Clearance." Accordingly, if you own a beneficial interest in a global note, then you are not considered an owner or holder of the notes. Instead, DTC or its nominee is the sole holder of the notes. Unlike persons who have certificated notes registered in their names, owners of beneficial interests in global notes do not have the direct right to act on our solicitations for consents or requests for waivers or other actions from holders. Instead, those beneficial owners are permitted to act only to the extent that they have received appropriate proxies to do so from DTC or, if applicable, a DTC participant. The applicable procedures for the granting of these proxies may not be sufficient to enable owners of beneficial interests in global notes to vote on any requested actions on a timely basis. In addition, notices and other communications relating to the notes are sent to DTC. We expect DTC to forward any such communications to DTC participants, which in turn would forward such communications to indirect DTC participants. But we can make no assurances that you timely receive any such communications.

Risks Related to our Common Stock

The price of our common stock historically has been volatile. This volatility may affect the price at which you could sell the common stock you receive upon conversion of your notes, if any, and the sale of substantial amounts of our common stock could adversely affect the price of our common stock and the value of your notes.

The trading volume of our common stock has been limited since our common stock began publicly trading on the OTCQB in December 2015 and has remained limited on the NYSE American since our initial public offering in March 2016. This volatility may affect the price at which you could sell the common stock, if any, you receive upon conversion of your notes, and the sale of substantial amounts of our common stock could adversely affect the price of our common stock and the value of your notes. Our stock price is likely to continue to be volatile and subject to significant price and volume fluctuations in response to market and other factors, including variations in our quarterly operating results from our expectations or those of securities analysts or investors; downward revisions in securities analysts' estimates; announcement by us or our competitors of significant acquisitions, strategic partnerships, joint ventures or capital commitments; and the other factors discussed elsewhere in this prospectus and the documents incorporated by reference in this prospectus, or for reasons unrelated to our operations, such as reports by industry analysts, investor perceptions or negative announcements by our customers, competitors or suppliers regarding their own performance, as well as industry conditions and general financial, economic and political instability.

Because we do not anticipate paying any cash dividends on shares of our common stock in the foreseeable future, capital appreciation, if any, will be your sole source of gain if you convert your notes into common stock.

We have never declared or paid cash dividends on our common stock. We currently intend to retain all available funds and any future earnings for use in the operation and expansion of our business and do not

Table of Contents

anticipate paying any cash dividends in the foreseeable future. Our ability to pay dividends on shares of our common stock is further limited by restrictions on our ability to pay dividends or make distributions under the terms of the agreements governing our indebtedness, including the indenture governing the notes offered hereby, and may be limited by future similar agreements. Accordingly, if you convert your notes into common stock, you may have to sell some or all of your securities in order to generate cash flow from your investment. You may not receive a gain on your investment when you sell securities and you may lose the entire amount of the investment.

USE OF PROCEEDS

The selling securityholders will receive all of the proceeds from their sale from time to time under this prospectus and any accompanying prospectus supplement of the notes or the common stock issuable upon conversion of the notes. We will not receive any proceeds from these sales.

Table of Contents

DESCRIPTION OF NOTES

The notes were issued under an indenture (which we refer to as the "indenture") dated as of July 25, 2019, by and among us, Senseonics, Incorporated and U.S. Bank National Association, as trustee (which we refer to as the "trustee"). A copy of the indenture is filed as an exhibit to the registration statement of which this prospectus forms a part. The following summary of the terms of the notes and the indenture does not purport to be complete and is subject, and qualified in its entirety by reference, to the detailed provisions of the notes and the indenture. Those documents, and not this description, define a holder's legal rights as a holder of the notes. The terms of the notes include those expressly set forth in the indenture and those made part of the indenture by reference to the Trust Indenture Act of 1939, as amended (the "TIA"). For purposes of this summary, the terms "Senseonics," "we," "us" and "our" refer only to Senseonics Holdings, Inc. and notthe Registrant Guarantors is being filed solely to any of its subsidiaries, unless we specify otherwise. Unlessfile the context requires otherwise, the term "interest" includes defaulted interest, if any, payable pursuant to the indentureExhibits 4.2 and "additional interest" and "special interest" payable pursuant to the provisions described under "— Events of Default."

General

On July 25, 2019, we issued $82.0 million in aggregate principal amount of our 5.25% convertible senior notes due 2025 (the "notes") under the indenture. The notes bear interest at a rate of 5.25% per annum, payable semi-annually in arrears on January 15 and July 15 of each year, beginning on January 15, 2020, to holders of record at the close of business on the preceding January5.1. This Amendment No. 1 and July 1 immediately preceding the January 15 and July 15 interest payment dates, respectively, except as described below.

The notes:

§

are general unsecured, senior obligations;



§

are limited to an aggregate principal amount of $82.0 million;



§

bear cash interest from July 25, 2019 at an annual rate of 5.25% payable on January 15 and July 15 of each year, beginning on January 15, 2020;



§

are subject to redemption at our option, in whole or in part, if (1) the last reported sale price of our common stock has been at least 150% of the conversion price then in effect for at least 20 trading days (whether or not consecutive) during any 30 consecutive trading day period (including the last trading day of such period) ending on, and including, the trading day immediately preceding the date on which we provide notice of redemption and (2) a registration statement covering the resale of the shares of our common stock issuable upon conversion of the notes is effective and available for use and is expected to remain effective and available for use during the redemption period (as defined below) as of the date the redemption notice date, at a redemption price equal to 100% of the principal amount of the notes to be redeemedplus accrued and unpaid interest to, but excluding, the redemption date;



§

mature on January 15, 2025 (the "maturity date"), unless earlier converted, redeemed or repurchased;



§

are subject to repurchase by us at the option of the holders following a fundamental change (as defined below under "— Fundamental Change Permits Holders to Require Us to Repurchase Notes"), at a fundamental change repurchase price equal to 100% of the principal amount of the notes to be repurchased,plus accrued and unpaid interest to, but excluding, the fundamental change repurchase date;



§

are subject to other covenants, as described under "— Covenants;"



§

are subject to certain restrictions on transfer and a resale registration rights agreement, as described under "— Rule 144 Resales and Registration Rights;"



§

are issued in denominations of $1,000 and integral multiples of $1,000;

Table of Contents

§

are represented by one or more registered notes in global form, but in certain limited circumstances may be represented by notes in definitive form. See "— Book-Entry, Settlement and Clearance;" and



§

are unconditionally guaranteed on a senior basis by the subsidiary guarantors (as defined below).

The notes are guaranteed by the "subsidiary guarantors," which include Senseonics, Incorporated, our sole subsidiary as of the date of this prospectus, and each of our restricted subsidiaries formed or acquired after the date of the initial issuance of the notes that is not an Excluded Subsidiary (as defined below). The subsidiary guarantees may be released under certain circumstances. See "— Covenants — Future Subsidiary Guarantees" and "— Subsidiary Guarantees."

Subject to satisfaction of certain conditions, the notes may be converted at an initial conversion rate of 757.5758 shares of common stock per $1,000 principal amount of notes (equivalent to an initial conversion price of approximately $1.32 per share of common stock). The conversion rate is subject to adjustment if certain events occur as described under "— Conversion Rights — Conversion Rate Adjustments."

Upon conversion of a note, we will deliver shares of our common stock, together with a cash payment in lieu of delivering any fractional share, as described under "Conversion Rights — Settlement upon Conversion," and, if applicable, a cash payment as described under "— Conversion Rights — Special Settlement Provisions in Connection with a Make-Whole Fundamental Change or Redemption Period." You will not receive any separate cash payment for interest, if any, accrued and unpaid to the conversion date except under the limited circumstances described below under "— Conversion Rights — General."

However, you will not be entitled to receive any shares of our common stock otherwise deliverable upon conversion of the notes to the extent, but only to the extent, that such receipt would cause you to become, directly or indirectly, a "beneficial owner" of shares of our common stock in excess of the beneficial ownership limits applicable to you at such time.

We are not permitted to reopen the indenture to provide for the issuance of any additional notes.

We do not intend to list the notes on any securities exchange or any automated dealer quotation system.

Except to the extent the context otherwise requires, we use the term "notes" in this prospectus to refer to each $1,000 principal amount of notes. We use the term "common stock" in this prospectus to refer to our common stock, par value $0.001 per share. References in this prospectus to a "holder" or "holders" of notes that are held through The Depository Trust Company ("DTC") are references to owners of beneficial interests in such notes, unless the context otherwise requires. However, we and the trustee will treat the person in whose name the notes are registered (Cede & Co., in the case of notes held through DTC) as the owner of such notes for all purposes. References herein to the "close of business" refer to 5:00 p.m., New York City time, and to the "open of business" refer to 9:00 a.m., New York City time.

Purchase and Cancellation

We will cause all notes surrendered for payment, repurchase (but excluding notes repurchased pursuant to cash-settled swaps or other derivatives), including as described immediately below and in "— Fundamental Change Permits Holders to Require Us to Repurchase Notes," redemption, registration of transfer or exchange or conversion, if surrendered to any person that we control other than the trustee, to be delivered to the trustee for cancellation and they will no longer be considered "outstanding" under the indenture upon their payment, repurchase, registration of transfer or exchange or conversion. All notes delivered to the trustee shall be cancelled promptly by the trustee. Except for notes surrendered for registration of transfer or exchange, no notes shall be authenticated in exchange for any notes cancelled as provided in the indenture.

Table of Contents

We may, to the extent permitted by law, and directly or indirectly (regardless of whether such notes are surrendered to us), repurchase notes in the open market or otherwise, whether by us or our subsidiaries or through a privately negotiated transaction or public tender or exchange offer or through counterparties to private agreements, including by cash-settled swaps or other derivatives, in each case, without prior notice to the holders of the notes.

Payments on the Notes; Paying Agent and Registrar; Transfer and Exchange

We will pay or cause the paying agent to pay the principal of, and interest on, notes in global form registered in the name of or held by DTC or its nominee by wire transfer in immediately available funds to DTC or its nominee, as the case may be, as the registered holder of such global note.

We will pay or cause the paying agent to pay the principal of any certificated notes at the office or agency designated by us for that purpose. We have initially designated the trustee as our paying agent and registrar and its corporate trust office as a place where notes may be presented for payment or for registration of transfer. We may, however, change the paying agent or registrar without giving prior notice to the holders of the notes, and we may act as paying agent or registrar. Interest on certificated notes will be payable (i) to holders holding certificated notes having an aggregate principal amount of $5,000,000 or less, by check mailed to the holders of these notes and (ii) to holders holding certificated notes having an aggregate principal amount of more than $5,000,000, either by check mailed to each such holder or, upon written application by such holder to the registrar not later than the relevant regular record date, by wire transfer in immediately available funds to that holder's account within the United States if such holder has provided us, the trustee or the paying agent with the requisite information necessary to make such wire transfer, which application shall remain in effect until the holder notifies, in writing, the registrar to the contrary.

A holder of notes may transfer or exchange notes at the office of the registrar in accordance with the indenture. The registrar and the trustee may require a holder, among other things, to furnish appropriate endorsements and transfer documents. No service charge will be imposed by us, the trustee or the registrar for any registration of transfer or exchange of notes, but we may require a holder to pay a sum sufficient to cover any transfer tax or other similar governmental charge required by law or permitted by the indenture. We are not required to transfer or exchange any note selected for redemption or surrendered for conversion or required repurchase. A holder of a beneficial interest in a note in global form may transfer or exchange such beneficial interest in accordance with the indenture and the applicable procedures of DTC. See "— Book-Entry, Settlement and Clearance."

The registered holder of a note will be treated as its owner for all purposes.

Interest

The notes bear cash interest at a rate of 5.25% per year until maturity. Interest on the notes accrues from July 25, 2019 or from the most recent date on which interest has been paid or duly provided for. Interest is payable semiannually in arrears on January 15 and July 15 of each year, beginning on January 15, 2020.

Interest will be paid to the person in whose name a note is registered at the close of business on January 1 or July 1 (whether or not a business day (as defined below)), as the case may be, immediately preceding the relevant interest payment date (each, a "regular record date"). Interest on the notes will be computed on the basis of a 360-day year composed of 12 30-day months and, for partial months, on the basis of the number of days actually elapsed in a 30-day month.

If any interest payment date, the maturity date or any earlier required repurchase date upon a fundamental change of a note falls on a day that is not a business day, the required payment will be made on the next succeeding business day with the same force and effect as if made on such scheduled payment date, and no interest on such payment will accrue in respect of the delay. The term "business day" means, with respect to any note, any day other than a Saturday, a Sunday or a day on which the Federal Reserve Bank

Table of Contents

of New York is authorized or required by law or executive order to close or be closed or a day when the corporate trust office of the trustee or the depository is closed.

Unless the context otherwise requires, all references to interest in this prospectus include additional interest, if any, payable as described under "— Rule 144 Resales and Registration Rights" and at our election as the sole remedy during certain periods for an event of default relating to the failure to comply with our reporting obligations as described under "— Events of Default."

Ranking

The notes:

§

rank senior in right of payment to all of our existing and future indebtedness that is expressly subordinated in right of payment to the notes;



§

rank equal in right of payment with all of our existing and future unsecured, senior indebtedness, including the 2023 notes (as defined under "— Covenants — Certain Definitions");



§

rank structurally junior in right of payment to all the liabilities, including trade payables, of any of our subsidiaries that are not subsidiary guarantors; and



§

are effectively subordinated to all of our existing and future secured indebtedness (including the indebtedness under the Credit Agreement (as defined under "— Covenants — Incurrence of Indebtedness and Issuance of Preferred Stock")) to the extent of the value of the assets or property securing such indebtedness.

Our operations are conducted through our subsidiary and, therefore, we depend on the cash flow of our subsidiary to meet our obligations, including our obligations under the notes. In addition, the ability of our subsidiaries to pay dividends and make other payments to us is restricted by, among other things, applicable corporate and other laws and regulations as well as agreements to which our subsidiaries may become a party. In the event of our bankruptcy, liquidation, reorganization or other winding up, our assets will be available to pay obligations on the notes only after secured indebtedness has been repaid in full from the assets securing such indebtedness. We advise you that there may not be sufficient assets remaining to pay amounts due on any or all the notes then outstanding.

As of July 31, 2019, the principal amount of our total consolidated indebtedness was $142.7 million, of which $45.0 million was senior secured indebtedness of us and our sole subsidiary and subsidiary guarantor under the Credit Agreement and $97.7 million was our senior unsecured indebtedness under the notes and the 2023 notes. Our sole subsidiary guarantor had $127.0 million principal amount of indebtedness as of July 31, 2019. We may not be able to pay cash for the fundamental change repurchase price upon a fundamental change if a holder requires us to repurchase notes as described below. See "Risk Factors — Risks Related to the Notes — We may not have the ability to raise the funds necessary to repurchase the notes upon a fundamental change, and our future debt may contain certain limitations on our ability to repurchase the notes."

Subsidiary Guarantees

Our subsidiary guarantors, jointly and severally, fully and unconditionally guarantee our payment obligations under the notes. Each subsidiary guarantee:

§

is a general unsecured, senior obligation of each subsidiary guarantor;



§

ranks senior in right of payment to all of the existing and future liabilities that are expressly subordinated in right of payment to the subsidiary guarantee;



§

ranks equal in right of payment with all of the existing and future unsecured, senior indebtedness of each subsidiary guarantor; and

Table of Contents

§

is effectively subordinated to all of our existing and future secured indebtedness (including the indebtedness under the Credit Agreement) to the extent of the value of the assets or property securing such indebtedness.

Under the terms of the full and unconditional guarantees, holders of the notes are not required to exercise their remedies against us before they proceed directly against the subsidiary guarantors.

The obligations of each subsidiary guarantor under its subsidiary guarantee are limited as necessary to prevent that subsidiary guarantee from constituting a fraudulent conveyance, fraudulent transfer or unlawful financial assistance under applicable law or otherwise to reflect limitations under applicable law. By virtue of these limitations, the obligations of a subsidiary guarantor under its subsidiary guarantee could be significantly less than amounts payable with respect to the notes or a subsidiary guarantor may have effectively no obligations under its respective subsidiary guarantee. See "Risk Factors — Risks Related to the Notes — Federal and state statues allow courts, under specific circumstances, to void notes and guarantees and require noteholders to return payments received."

The notes are not and will not be guaranteed by (a) any subsidiary that is prohibited by any applicable law or, on the date such subsidiary is acquired (provided, that such prohibition is not be created in contemplation of such acquisition), its organizational documents, in each case, from guaranteeing the notes; (b) any subsidiary that is prohibited by any contractual obligation that existed on the date any such subsidiary is acquired (provided, that such prohibition is not created in contemplation of such acquisition) from guaranteeing the notes; (c) any subsidiary to the extent that the provision of any subsidiary guarantee of the notes would require the consent, approval, license or authorization of any governmental authority which has not been obtained, any subsidiary that is subject to such restrictions (provided that after such time that such restrictions on subsidiary guarantees are waived, lapse, terminate or are no longer effective, such subsidiary shall no longer be an Excluded Subsidiary by virtue of this clause (c)); (d) any wholly-owned Subsidiary organized under the laws of the United States, any state of the United States or the District of Columbia that (i) has no material assets other than Capital Stock of one or more subsidiaries that are "controlled foreign corporations" within the meaning of Section 957(a) of the Code or (ii) is a subsidiary of a subsidiary that is a "controlled foreign corporation" within the meaning of Section 957(a) of the Code (provided any subsidiary described in the foregoing clauses (d)(i) or (d)(ii) shall be an Excluded Subsidiary only with respect to the subsidiary guarantee of an obligation of a United States person); (e) any Subsidiary that is not incorporated or organized under the laws of the United States, any state of the United States or the District of Columbia; (f) any Unrestricted Subsidiary; and (g) any subsidiary for which the provision of a subsidiary guarantee would result in a material adverse tax or regulatory consequence to us or one of our subsidiaries, as applicable (collectively, the "Excluded Subsidiaries").

The subsidiary guarantee of a subsidiary guarantor will be automatically and unconditionally released:

§

in connection with any sale or other disposition of all of the assets of that subsidiary guarantor (including by way of merger or consolidation) to a person that is not (either before or after giving effect to such transaction) us or one of our restricted subsidiaries or affiliates if the sale or other disposition does not violate the "Asset Sales" covenant in the indenture (for the avoidance of doubt, it is understood that the acquiror of such assets only shall be released from the subsidiary guarantee and not the seller or other transferor of such assets);



§

in connection withmodify any sale or other disposition of Capital Stock of that subsidiary guarantor to a Person that is not (either before or after giving effect to such transaction) us or one of our restricted subsidiaries or affiliates, if the sale or other disposition does not violate the "Asset Sales" covenant in the indenture and that subsidiary guarantor ceases to be our restricted subsidiary as a result of the sale or other disposition;



§

upon covenant defeasance or satisfaction and discharge of the indenture;



§

upon the liquidation or dissolution of such subsidiary guarantor following the transfer of all of its assets to us or another subsidiary guarantor; or

Table of Contents

§

in the case of a subsidiary guarantee provided by a subsidiary guarantor as a result of its guarantee of any other indebtedness of the Company or any subsidiary guarantor pursuant to the covenant described below under the caption "— Covenants — Future Subsidiary Guarantees," the release of such guarantor from the relevant indebtedness.

Notwithstanding the foregoing, no subsidiary guarantor shall be released from its subsidiary guarantee for so long as such subsidiary guarantor guarantees or provides credit support for, any of our or our other restricted subsidiaries' indebtedness.

Under the circumstances described below under "— Covenants — Designation of Restricted and Unrestricted Subsidiaries," we will be permitted to designate certain of our subsidiaries as "unrestricted subsidiaries." Unrestricted subsidiaries will not be subject to many of the restrictive covenants in the indenture and will not guarantee the notes. If we have any unrestricted subsidiaries in the future, the notes will be effectively subordinated in right of payment to all indebtedness, including trade payables, of such unrestricted subsidiaries. In the event of a bankruptcy, liquidation or reorganization of any of these unrestricted subsidiaries, the unrestricted subsidiaries will pay the holders of their debt and their trade creditors before they will be able to distribute any of their assets to us or any subsidiary guarantors.

Optional Redemption

No "sinking fund" is provided for the notes, which means that we are not required to redeem or retire the notes periodically. We may redeem for cash all or part of the notes, at our option, if (1) the last reported sale price of our common stock has been at least 150% of the conversion price then in effect for at least 20 trading days (whether or not consecutive) during any 30 consecutive trading day period (including the last trading day of such period) ending on, and including, the trading day immediately preceding the date on which we provide notice of redemption (a "redemption notice date") and (2) a registration statement covering the resale of the shares of our common stock issuable upon conversion of the notes is effective and available for use and is expected to remain effective and available for use during the redemption period as of the date the redemption notice date. In the case of any redemption, we will provide not less than 20 nor more than 60 calendar days' notice before the redemption date to the trustee, the paying agent and the holder of notes, and the redemption price will be equal to 100% of the principal amount of the notes to be redeemedplus accrued and unpaid interest to, but excluding, the redemption date. The redemption date must be a business day.

Notwithstanding the foregoing, if we set a redemption date between a regular record date and the corresponding interest payment date, we will not pay accrued interest to any holder of notes to be redeemed, and will instead pay the full amount of the relevant interest payment on such interest payment date to the holder of record on such regular record date.

With respect to any notes that are called for redemption and converted from and including the redemption notice date until the close of business on the business day immediately preceding the redemption date (any such period, a "redemption period") as described under "— Conversion Rights — General," we will, under certain circumstances, increase the conversion rate for the notes so surrendered for conversion by a number of additional shares as described under "— Conversion Rights — Increase in Conversion Rate upon Conversion upon a Make-Whole Fundamental Change or during a Redemption Period."

Subject to the applicable rules and procedures of DTC, if we decide to redeem fewer than all of the outstanding notes, we will instruct the trustee regarding the selection of notes to be redeemed (in principal amounts of $1,000 or multiples thereof) by lot, on a pro rata basis or by another method we consider to be fair and appropriate.

If a portion of your note is selected for partial redemption and you convert a portion of the same note, the converted portion will be deemed to be from the portion selected for redemption.

In the event of any redemption in part, we will not be required to register the transfer of or exchange any note so selected for redemption, in whole or in part, except the unredeemed portion thereof.

The notes may not be redeemed if the principal amount of the notes has been accelerated, and such acceleration has not been rescinded, on or prior to the redemption date (except in the case of an acceleration resulting from a default by us in the payment of the redemption price with respect to the notes).

The "last reported sale price" of our common stock on any date means the closing sale price per share (or if no closing sale price is reported, the average of the bid and ask prices or, if more than one in either case, the average of the average bid and the average ask prices) on that date as reported in composite transactions for the principal U.S. national or regional securities exchange on which our common stock is traded. If our common stock is not listed for trading on a U.S. national or regional securities exchange on the relevant date, the "last reported sale price" will be the last quoted bid price for our common stock in the over-the-counter market on the relevant date as reported by OTC Markets Group Inc. or a similar organization. If our common stock is not so quoted, the "last reported sale price" will be the average of the mid-point of the last bid and ask prices for our common stock on the relevant date from each of at least three nationally recognized independent investment banking firms selected by us for this purpose.

"Trading day" means a day on which (i) trading in our common stock (or other security for which a closing sale price must be determined) generally occurs on The NYSE American or, if our common stock (or such other security) is not then listed or quoted on The NYSE American, on the principal other U.S. national or regional securities exchange on which our common stock (or such other security) is then listed or, if our common stock (or such other security) is not then listed on a U.S. national or regional securities exchange, on the principal other market on which our common stock (or such other security) is then traded, and (ii) a last reported sale price for our common stock (or closing sale price for such other security) is available on such securities exchange or market. If our common stock (or such other security) is not so listed or traded, "trading day" means a "business day."

Conversion Rights

General

Holders may convert all or any portion of their notes at their option at any time prior to the close of business on the business day immediately preceding the maturity date.

The initial conversion rate is 757.5758 shares of common stock per $1,000 principal amount of notes (equivalent to an initial conversion price of approximately $1.32 per share of common stock).

The conversion rate is subject to adjustment if certain events occur. The conversion price at any given time will be computed by dividing $1,000 by the applicable conversion rate at such time. Accordingly, an adjustment to the conversion rate will result in a corresponding (but inverse) adjustment to the conversion price.

Upon conversion of a note, we will satisfy our conversion obligation by delivering shares of our common stock, together with a cash payment in lieu of delivering any fractional share, as set forth below under "— Settlement upon Conversion," and, if applicable, a cash payment as described under "— Conversion Rights — Special Settlement Provisions in Connection with a Make-Whole Fundamental Change or Redemption Period." We will settle our conversion obligation on the second business day immediately following the relevant conversion date. The trustee will initially act as the conversion agent.

A holder may convert fewer than all of such holder's notes so long as the notes converted are an integral multiple of $1,000 principal amount.

Table of Contents

Upon conversion, you will not receive any separate cash payment for accrued and unpaid interest, if any, except as described below. We will not issue fractional shares of our common stock upon conversion of notes. Instead, we will pay cash in lieu of delivering any fractional share as described under "— Conversion Rights — Settlement upon Conversion." Our delivery to you of the full number of shares, together with a cash payment for any fractional share, into which a note is convertible will be deemed to satisfy in full our obligation to pay:

§

the principal amount of the note; and



§

accrued and unpaid interest, if any, to, but not including, the relevant conversion date.

As a result, accrued and unpaid interest, if any, to, but not including, the relevant conversion date will be deemed to be paid in full rather than cancelled, extinguished or forfeited.

Notwithstanding the immediately preceding paragraph, if notes are converted after the close of business on a regular record date for the payment of interest, but prior to the open of business on the immediately following interest payment date, holders of such notes at the close of business on such regular record date will receive the full amount of interest payable on such notes on the corresponding interest payment date notwithstanding the conversion. However, notes surrendered for conversion during the period from the close of business on any regular record date to the open of business on the immediately following interest payment date must be accompanied by funds equal to the amount of interest payable on the notes so converted on the corresponding interest payment date (regardless of whether the holder was the holder of record on the corresponding regular record date);provided that no such payment need be made:

§

for conversions following the regular record date immediately preceding the maturity date;



§

if we have specified a redemption date that is after a regular record date and on or prior to the business day immediately following the corresponding interest payment date, in respect of notes converted;



§

if we have specified a fundamental change repurchase date that is after a regular record date and on or prior to the business day immediately following the corresponding interest payment date, in respect of notes converted; or



§

to the extent of any overdue interest, if any overdue interest exists at the time of conversion with respect to such note.

Conversion Procedures

If you hold a beneficial interest in a global note, to convert you must comply with DTC's procedures for converting a beneficial interest in a global note and, if required, pay funds equal to interest payable on the next interest payment date to which you are not entitled and, if required, pay all transfer or similar taxes, if any. As such, if you are a beneficial owner of the notes, you must allow for sufficient time to comply with DTC's procedures if you wish to exercise your conversion rights. Your exercise of such conversion rights shall be irrevocable.

If you hold a certificated note, to convert you must:

§

complete and manually sign the conversion notice on the back of the note, or a facsimile of the conversion notice;



§

deliver the conversion notice, which is irrevocable, and the note to the conversion agent;



§

if required, furnish appropriate endorsements and transfer documents;



§

if required, pay funds equal to the interest payable on the next interest payment date to which you are not entitled; and



§

if required, pay all transfer or similar taxes, if any.

In addition, a holder may be required to provide a certification to us as to whether the person (or persons) receiving shares of our common stock upon conversion is, or would, as a result of such conversion, become the beneficial owner of shares of our common stock outstanding at such time in excess of any beneficial ownership limit then applicable to such person (or persons). See "— Conversion Rights — Limits on the Issuance of Shares of Common Stock upon Conversion."

Table of Contents

We will pay any documentary, stamp or similar issue or transfer tax on the issuance of the shares of our common stock upon conversion of the notes, unless the tax is due because the holder requests such shares to be issued in a name other than the holder's name, in which case the holder must pay the tax.

We refer to the date you comply with the relevant procedures for conversion described above as the "conversion date."

If a holder has already delivered a repurchase notice as described under "— Fundamental Change Permits Holders to Require Us to Repurchase Notes" with respect to a note, the holder may not surrender that note for conversion until the holder has withdrawn the repurchase notice in accordance with the relevant provisions of the indenture. If a holder submits its notes for required repurchase, the holder's right to withdraw the repurchase notice and convert the notesprospectus that are subject to repurchase will terminate at the close of business on the business day immediately preceding the relevant fundamental change repurchase date.

Limits on Issuance of Shares of Common Stock upon Conversion

Notwithstanding anything to the contrary herein, no person will be entitled to receive any shares of our common stock otherwise deliverable upon conversion of the notes to the extent, but only to the extent, that such receipt would cause such person to become, directly or indirectly, a "beneficial owner" (as defined below) of more than 9.99% of the shares of our common stock outstanding at such time (such restriction, the "general beneficial ownership limit").

In addition, a holder of notes at its option may elect a beneficial ownership limit as to such holder (but not as to any other holder) that is less than or equal to the general beneficial ownership limit then applicable to the holders in general upon written notice delivered to us prior to the issuance of the notes or, if thereafter, at least 61 days prior to the date of effectiveness of such lower beneficial ownership limit, specifying the percentage of shares of our common stock for the beneficial ownership limit that shall apply to such holder (such beneficial ownership limit, a "holder beneficial ownership limit" and together with the general beneficial ownership limit, the "beneficial ownership limits").

Any purported delivery of shares of our common stock upon conversion of the notes shall be void and have no effect to the extent, but only to the extent, that such delivery would result in any person becoming the beneficial owner of shares of our common stock outstanding at such time in excess of the beneficial ownership limits applicable to such person.

Unless we have waived the general beneficial ownership limit as described below under "— Conversion Rights — Waiver of Beneficial Ownership Limits" and there is no holder beneficial ownership limit applicable to a holder, when such holder tenders notes for conversion, that holder must provide a certification to us as to whether the person (or persons) receiving shares of our common stock upon conversion is, or would, as a result of such conversion, become the beneficial owner of shares of our common stock outstanding at such time in excess of any beneficial ownership limit then applicable to such person (or persons).

If any delivery of shares of our common stock otherwise owed to any person (or persons) upon conversion of the notes is not made, in whole or in part, as a result of the applicable beneficial ownership limits, our obligation to make such delivery shall not be extinguished and, such holder may either:

§

request the return of the notes surrendered by such holder for conversion, after which we shall deliver such notes to such holder within two trading days after receipt of such request; or



§

certify to us that the person (or persons) receiving shares of our common stock upon conversion is not, and would not, as a result of such conversion, become the beneficial owner of shares of our common stock outstanding at such time in excess of the applicable beneficial ownership limits, after which we shall deliver any such shares of our common stock withheld on account of such applicable beneficial ownership limits by the later of (i) the date such shares were

Table of Contents

otherwise due to such person (or persons) and (ii) two trading days after receipt of such certification; provided, however, until such time as the affected holder gives such notice, no person shall be deemed to be the stockholder of record with respect to the shares of our common stock otherwise deliverable upon conversion in excess of any applicable beneficial ownership limit. Upon delivery of such notice, the provisions under "Conversion Rights — Settlement upon Conversion," shall apply to the shares of common stock to be delivered pursuant to such notice.

For purposes of this section only, a person shall be deemed the "beneficial owner" of and shall be deemed to beneficially own any shares of our common stock that such person or any of such person's affiliates (as defined in Rule 12b-2 under the Exchange Act) or associates (as defined in Rule 12b-2 under the Exchange Act) is deemed to beneficially own, together with any shares of our common stock beneficially owned by any other persons whose beneficial ownership would be aggregated with such person for purposes of Section 13(d) of the Exchange Act. Subject to the following proviso, for purposes of the this section only, beneficial ownership shall be determined in accordance with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder as in effect on the first date of original issuance of the notes; provided that the number of shares of our common stock beneficially owned by such person and its affiliates and associates and any other persons whose beneficial ownership would be aggregated with such person for purposes of Section 13(d) of the Exchange Act shall include the number of shares of our common stock issuable upon exercise or conversion of any of our securities or rights to acquire our common stock, whether or not such securities or rights are currently exercisable or convertible or are exercisable or convertible only after the passage of time (including the number of shares of our common stock issuable upon conversion of the notes in respect of which the beneficial ownership determination is being made), but shall exclude the number of shares of our common stock that would be issuable upon (A) conversion of the remaining, unconverted portion of any notes beneficially owned by such person or any of its affiliates or associates and any other persons whose beneficial ownership would be aggregated with such person for purposes of Section 13(d) of the Exchange Act and (B) exercise or conversion of the unexercised or unconverted portion of any of our other securities subject to a limitation on conversion or exercise analogous to the limitation contained herein beneficially owned by such person or any of its affiliates or associates and any other persons whose beneficial ownership would be aggregated with such person for purposes of Section 13(d) of the Exchange Act. For the avoidance of doubt, the term "beneficial owner" as used in this section shall not include (i) with respect to any global note, the nominee of the depositary or any person having an account with the depositary or its nominee or (ii) with respect to any certificated note, the holder of such certificated note unless, in each case, such nominee, account holder or holder shall also be a beneficial owner of such note.

Waiver of Beneficial Ownership Limits

We may, at our option with the approval of our board of directors and subject to the applicable listing standards of NYSE American, waive the general beneficial ownership limit (as to a particular person or as to all persons). In the event that we exercise our right to waive the general beneficial ownership limit to all persons, we or, at our written request and our expense, the trustee, shall deliver or cause to be delivered to each holder 61 days prior to the effective waiver date an irrevocable notice stating that as of an effective date specified therein, we waive any restrictions that limit a holder from converting its notes in the event that such holder is, or would, as a result of a conversion of notes, become, a restricted converting holder. Any such waiver of the general beneficial ownership limit would not effect a waiver of any holder beneficial ownership limit.

Settlement upon Conversion

Except as described under "— Conversion Rights — Special Settlement Provisions in Connection with a Make-Whole Fundamental Change or Redemption Period," upon conversion, we will deliver to holders in respect of each $1,000 principal amount of notes being converted a number of shares of our common stock equal to the conversion rate, together with a cash payment in lieu of delivering any fractional share of

Table of Contents

common stock issuable upon conversion based on the last reported sale price of our common stock on the relevant conversion date. We will deliver the consideration due in respect of conversion on the second business day immediately following the relevant conversion date.

Each conversion will be deemed to have been effected as to any notes surrendered for conversion on the conversion date, and the person in whose name the shares of our common stock shall be issuable upon such conversion will become the holder of record of such shares as of the close of business on such conversion date.

Conversion Rate Adjustments

The conversion rate will be adjusted by us as described below, except that we will not make any adjustments to the conversion rate if holders of the notes participate (other than in the case of (x) a share split or share combination or (y) a tender or exchange offer), at the same time and upon the same terms as holders of our common stock and solely as a result of holding the notes, in any of the transactions described below without having to convert their notes as if they held a number of shares of our common stock equal to the conversion rate, multiplied by the principal amount (expressed in thousands) of notes held by such holder.

(1)

If we exclusively issue shares of our common stock as a dividend or distribution on shares of our common stock, or if we effect a share split or share combination, the conversion rate will be adjusted based on the following formula:

where

Any adjustment made under this clause (1) shall become effective immediately after the close of business on the record date for such dividend or distribution, or immediately after the open of business on the effective date for such share split or share combination, as applicable. If any dividend or distribution of the type described in this clause (1) is declared but not so paid or made, the conversion rate shall be immediately readjusted, effective as of the date our board of directors or a committee thereof determines not to pay such dividend or distribution, to the conversion rate that would then be in effect if such dividend or distribution had not been declared.

(2)

If we distribute to all or substantially all holders of our common stock any rights, options or warrants (other than pursuant to a stockholder rights plan) entitling them, for a period of not more than 45 calendar days after the announcement date of such distribution, to subscribe for or purchase shares of our common stock at a price per share that is less than the average of the last reported sale prices of our common stock for the 10 consecutive trading day period ending on, and

Table of Contents

including, the trading day immediately preceding the date of announcement of such distribution, the conversion rate will be increased based on the following formula:

where

Any increase made under this clause (2) will be made successively whenever any such rights, options or warrants are distributed and shall become effective immediately after the close of business on such record date for such distribution. To the extent that such rights, options or warrants are not exercised prior to their expiration or shares of our common stock are not delivered after the expiration of such rights, options or warrants, the conversion rate shall be decreased to the conversion rate that would then be in effect had the increase with respect to the distribution of such rights, options or warrants been made on the basis of delivery of only the number of shares of common stock actually delivered. If such rights, options or warrants are not so distributed or if no such rights, options or warrants are not exercised prior to their expiration, the conversion rate shall be decreased to the conversion rate that would then be in effect if such record date for such distribution had not occurred.

For the purpose of this clause (2), in determining whether any rights, options or warrants entitle the holders to subscribe for or purchase shares of our common stock at less than such average of the last reported sale prices for the 10 consecutive trading day period ending on, and including, the trading day immediately preceding the date of announcement of such distribution, and in determining the aggregate offering price of such shares of our common stock, there shall be taken into account any consideration received by us for such rights, options or warrants and any amount payable on exercise or conversion thereof, the value of such consideration, if other than cash, to be determined by us in good faith and in a commercially reasonable manner.

(3)

If we distribute shares of our Capital Stock, evidences of our indebtedness, other assets or property of ours or rights, options or warrants to acquire our Capital Stock or other securities, to all or substantially all holders of our common stock, excluding:



§

dividends, distributions or issuances as to which an adjustment was effected pursuant to clause (1) or (2) above;



§

except as otherwise described below, rights issued pursuant to any stockholder rights plan of ours then in effect;



§

dividends or distributions paid exclusively in cash as to which the provisions set forth in clause (4) below shall apply;

Table of Contents

§

any dividends or distributions of reference property issued in exchange for our common stock as described under "— Conversion Rights — Recapitalizations, Reclassifications and Changes of Our Common Stock;" and



§

spin-offs as to which the provisions set forth below in this clause (3) shall apply;

then the conversion rate will be increased based on the following formula:

where

Any increase made under the portion of this clause (3) above will become effective immediately after the close of business on the record date for such distribution. If such distribution is not so paid or made, the conversion rate shall be decreased to be the conversion rate that would then be in effect if such distribution had not been declared. In the case of any distribution of rights, options or warrants, to the extent such rights options or warrants expire unexercised, the applicable conversion rate shall be immediately readjusted to the applicable conversion rate that would then be in effect had the increase made for the distribution of such rights, options or warrants been made on the basis of delivery of only the number of shares of our common stock actually delivered upon exercise of such rights, options or warrants. Notwithstanding the foregoing, if "FMV" (as defined above) is equal to or greater than "SP0" (as defined above), in lieu of the foregoing increase, each holder of a note shall receive, in respect of each $1,000 principal amount thereof, at the same time and upon the same terms as holders of our common stock, the amount and kind of our Capital Stock, evidences of our indebtedness, other assets or property of ours or rights, options or warrants to acquire our Capital Stock or other securities that such holder would have received if such holder owned a number of shares of common stock equal to the conversion rate in effect on the record date for the distribution.

With respect to an adjustment pursuant to this clause (3) where there has been a payment of a dividend or other distribution on our common stock of shares of Capital Stock of any class or series, or similar equity interest, of or relating to a subsidiary or other business unit, that are, or, when issued, will be, listed or admitted for trading on a U.S. national securities exchange, which we refer to as a "spin-off," the conversion rate will be increased based on the following formula:

where

Table of Contents

The increase to the conversion rate under the preceding paragraph will occur at the close of business on the last trading day of the valuation period;provided that in respect of any conversion of notes, if the relevant conversion date occurs during the valuation period, the reference to "10" in the preceding paragraph shall be deemed replaced with such lesser number of trading days as have elapsed between the ex-dividend date for such spin-off and such conversion date in determining the conversion rate. If any dividend or distribution that constitutes a spin-off is declared but not so paid or made, the conversion rate shall be immediately decreased, effective as of the date our board of directors or a committee thereof determines not to pay or make such dividend or distribution, to the conversion rate that would then be in effect if such dividend or distribution had not been declared or announced.

(4)

If we pay or make any cash dividend or distribution to all or substantially all holders of our common stock, the conversion rate will be adjusted based on the following formula:

where

Any increase to the conversion rate made under this clause (4) shall become effective immediately after the close of business on the record date for such dividend or distribution. If such dividend or distribution is not so paid, the conversion rate shall be decreased, effective as of the date our board of directors or a committee thereof determines not to make or pay such dividend or distribution, to be the conversion rate that would then be in effect if such dividend or distribution had not been declared.

Notwithstanding the foregoing, if "C" (as defined above) is equal to or greater than "SP0" (as defined above), in lieu of the foregoing increase, each holder of a note shall receive, for each $1,000 principal amount of notes, at the same time and upon the same terms as holders of shares of our common stock, the amount of cash that such holder would have received if such holder owned a number of shares of our common stock equal to the conversion rate on the record date for such cash dividend or distribution.

(5)

If we or any of our subsidiaries make a payment pursuant to a tender or exchange offer for our common stock that is subject to the then-applicable tender offer rules under the Exchange Act

Table of Contents

(other than any odd-lot tender offer), to the extent that the cash and value of any other consideration included in the payment per share of our common stock exceeds the average of the last reported sale prices of our common stock over the 10 consecutive trading day period commencing on, and including, the trading day next succeeding the last date on which tenders or exchanges may be made pursuant to such tender or exchange offer (the last date on which tenders or exchanges may be made pursuant to such tender or exchange offer, the "expiration date"), the conversion rate will be increased based on the following formula:

where

The increase to the conversion rate under the preceding paragraph will occur at the close of business on the 10th trading day immediately following, and including, the trading day next succeeding the date such tender or exchange offer expires;provided that in respect of any conversion of notes, if the relevant conversion date occurs during the 10 trading days immediately following, and including, the trading day next succeeding the expiration date of any tender or exchange offer, references to "10" or "10th" in the preceding paragraph shall be deemed replaced with such lesser number of trading days as have elapsed between the expiration date of such tender or exchange offer and such conversion date in determining the conversion rate.

In the event that we or one of our subsidiaries is obligated to purchase shares of our common stock pursuant to any such tender offer or exchange offer described in clause (5), but we are, or such subsidiary is, permanently prevented by applicable law from effecting any such purchase or all such purchases are rescinded, then the conversion rate shall again be adjusted to be the conversion rate that would then be in effect if such tender offer or exchange offer had not been made or had been made only in respect of the purchases that have been effected.

Except as stated herein, we will not adjust the conversion rate for the issuance of shares of our common stock or any securities convertible into or exchangeable for shares of our common stock or the right to purchase shares of our common stock or such convertible or exchangeable securities.

Table of Contents

As used in this section, "ex-dividend date" means the first date on which the shares of our common stock trade on the applicable exchange or in the applicable market, regular way, without the right to receive the issuance, dividend or distribution in question, from us or, if applicable, from the seller of our common stock on such exchange or market (in the form of due bills or otherwise) as determined by such exchange or market, and "effective date" means the first date on which the shares of our common stock trade on the applicable exchange or in the applicable market, regular way, reflecting the relevant share split or share combination, as applicable. For the avoidance of doubt, any alternative trading convention on the applicable exchange or market in respect of shares of our common stock under a separate ticker symbol or CUSIP number will not be considered "regular way" for this purpose.

As used in this section, "record date" means, with respect to any dividend, distribution or other transaction or event in which the holders of our common stock (or other applicable security) have the right to receive any cash, securities or other property or in which our common stock (or such other security) is exchanged for or converted into any combination of cash, securities or other property, the date fixed for determination of holders of our common stock (or such other security) entitled to receive such cash, securities or other property (whether such date is fixed by our board of directors or a duly authorized committee thereof, statute, contract or otherwise).

We are permitted to increase the conversion rate of the notes by any amount for a period of at least 20 business days if we determine that such increase would be in our best interest. We may also (but are not required to) increase the conversion rate to avoid or diminish income tax to holders of our common stock or rights to purchase shares of our common stock in connection with a dividend or distribution of shares (or rights to acquire shares) or similar event.

A holder may, in some circumstances, including a distribution of cash dividends to holders of our shares of common stock, be deemed to have received a distribution subject to U.S. federal income tax as a result of an adjustment or the nonoccurrence of an adjustment to the conversion rate. For a discussion of the U.S. federal income tax treatment of an adjustment to the conversion rate, see "Certain U.S. Federal Income Tax Considerations."

If we have a rights plan in effect upon conversion of the notes into common stock, you will receive, in addition to the shares of common stock received in connection with such conversion, the rights under the rights plan. However, if, prior to any conversion, the rights have separated from the shares of common stock in accordance with the provisions of the applicable rights plan, the conversion rate will be adjusted at the time of separation as if we distributed to all or substantially all holders of our common stock, shares of our Capital Stock, evidences of indebtedness, assets, property, rights, options or warrants as described in clause (3) above, subject to readjustment in the event of the expiration, termination or redemption of such rights. We currently do not have a stockholder rights plan in effect.

Notwithstanding any of the foregoing, the conversion rate will not be adjusted:

§

upon the issuance of shares of our common stock at a price below the conversion price or otherwise, other than any such issuance described in clause (1), (2) or (3) above;



§

upon the issuance of any shares of our common stock pursuant to any present or future plan providing for the reinvestment of dividends or interest payable on our securities and the investment of additional optional amounts in shares of our common stock under any plan;



§

upon the issuance of any shares of our common stock or options or rights to purchase those shares pursuant to any present or future employee, director or consultant benefit plan or program of or assumed by us or any of our subsidiaries;



§

upon the issuance of any shares of our common stock pursuant to any option, warrant, right or exercisable, exchangeable or convertible security not described in the preceding bullet and outstanding as of the date the notes were first issued;

Table of Contents

§

for a third-party tender offer by any party other than a tender offer by one or more of our subsidiaries as described in clause (5) above;



§

upon the repurchase of any of shares of our common stock pursuant to an open market share purchase program or other buy-back transaction, including structured or derivative transactions such as accelerated share repurchase transactions or similar forward derivatives, or other buy-back transaction, that is not a tender offer or exchange offer of the kind described under clause (5) above;



§

solely for a change in the par value of our common stock; or



§

for accrued and unpaid interest, if any.

If an adjustment to the conversion rate otherwise required by the provisions described above would result in a change of less than 1% to the conversion rate, then, notwithstanding the foregoing, we may, at our election, defer and carry forward such adjustment, except that all such deferred adjustments must be given effect immediately upon the earliest to occur of the following: (i) when all such deferred adjustments would result in an aggregate change of at least 1% to the conversion rate, (ii) on the conversion date for any notes and (iii) on the effective date of any make-whole fundamental change or redemption notice date, in each case, unless the adjustment has already been made, in each case, unless the adjustment has already been made.

Adjustments to the conversion rate will be calculated to the nearest 1/10,000th of a share.

Recapitalizations, Reclassifications and Changes of Our Common Stock

In the case of:

§

any recapitalization, reclassification or change of our common stock (other than a change to par value, or from par value to no par value, or changes resulting from a share split or share combination),



§

any consolidation, merger or combination involving us,



§

any sale, lease or other transfer to a third party of all or substantially all of our and our subsidiaries' consolidated assets, taken as a whole, or



§

any statutory share exchange,

in each case, as a result of which our common stock would be converted into, or exchanged for, stock, other securities, other property or assets (including cash or any combination thereof) (any such event, a "share exchange event"), then we or the successor or acquiring company, as the case may be, will execute with the trustee, without the consent of the holders, a supplemental indenture providing that, at and after the effective time of the share exchange event, the right to convert each $1,000 principal amount of notes will be changed into a right to convert such principal amount of notes into the kind and amount of shares of stock, other securities or other property or assets (including cash or any combination thereof) that a holder of a number of shares of common stock equal to the conversion rate immediately prior to such share exchange event would have owned or been entitled to receive (the "reference property") upon such share exchange event. However, at and after the effective time of the share exchange event, the number of shares of our common stock otherwise deliverable upon conversion of the notes as set forth under "— Conversion Rights — Settlement upon Conversion" above will be deliverable in the amount and type of reference property that a holder of that number of shares of our common stock would have received in such transaction. If the share exchange event causes our common stock to be converted into, or exchanged for, the right to receive more than a single type of consideration (determined based in part upon any form of stockholder election), the reference property into which the notes will be convertible will be deemed to be (i) the weighted average of the types and amounts of consideration received by the holders of our common stock that affirmatively make such an election or (ii) if no holders of our common stock affirmatively make such an election, the types and amounts of consideration actually received by the holders of our common stock. We will notify holders, the trustee and the conversion agent (if other than the trustee) of the weighted average as soon as practicable after such determination is made.

Table of Contents

If the reference property in respect of any share exchange event includes, in whole or in part, shares of common equity, the supplemental indenture providing that the notes will be convertible into reference property will also provide for anti-dilution and other adjustments that are as nearly equivalent as possible to the adjustments described under "— Conversion Rights — Conversion Rate Adjustments" above with respect to the portion of the reference property consisting of such common equity. If the reference property in respect of any such share exchange event includes shares of stock, securities or other property or assets (other than cash and/or cash equivalents) of a company other than us or the successor or purchasing company, as the case may be, in such share exchange event, such other company, if an affiliate of us or the successor or acquiring company, will also execute such supplemental indenture, and such supplemental indenture will contain such additional provisions to protect the interests of the holders, including the right of holders to require us to repurchase their notes upon a fundamental change as described under "— Fundamental Change Permits Holders to Require Us to Repurchase Notes" below, as we in good faith reasonably consider necessary by reason of the foregoing. We will agree in the indenture not to become a party to any such share exchange event unless its terms are consistent with the foregoing.

Adjustments of Prices

Whenever any provision of the indenture requires us to calculate the last reported sale prices over a span of multiple days (including, without limitation, the period, if any, for determining "stock price" for purposes of a make-whole fundamental change or notice of redemption), we will make appropriate adjustments in good faith and in a commercially reasonable manner (to the extent no corresponding adjustment is otherwise made pursuant to the provisions described under "— Conversion Rights — Conversion Rate Adjustments" above) to each to account for any adjustment to the conversion rate that becomes effective, or any event requiring an adjustment to the conversion rate where the ex-dividend date, effective date or expiration date of the event occurs, at any time during the period when the last reported sale prices are to be calculated.

For the avoidance of doubt, the adjustments made pursuant to the foregoing paragraph will be made, solely to the extent we determine in good faith and in a commercially reasonable manner that any such adjustment is appropriate, without duplication of any adjustment made pursuant to the provision set forth under "— Conversion Rights — Conversion Rate Adjustments."

Increase in Conversion Rate upon Conversion upon a Make-Whole Fundamental Change or during a Redemption Period

If the "effective date" (as defined below) of a "make-whole fundamental change" (as defined below) occurs prior to the maturity date of the notes and a holder elects to convert its notes in connection with such make-whole fundamental change, or we issue a notice of redemption as set forth under "— Optional Redemption" and a holder elects to convert its notes called for redemption, if any, during the related redemption period, we will, under certain circumstances, increase the conversion rate for the notes so surrendered for conversion by a number of additional shares of common stock (the "additional shares"), as described below. A "make-whole fundamental change" means any transaction or event that constitutes a fundamental change defined below in clause (1), (2) or (4) of the definition of "fundamental change" under "— Fundamental Change Permits Holders to Require Us to Repurchase Notes" below, after giving effect to any exceptions or exclusions from such definition, but without regard to theproviso in clause (2) of the definition thereof. A conversion of notes will be deemed for these purposes to be "in connection with" such make-whole fundamental change if the relevant conversion date occurs during the period from, and including, the effective date of the make-whole fundamental change up to, and including, the business day immediately prior to the related fundamental change repurchase date (or, in the case of a make-whole fundamental change that would have been a fundamental change but for theproviso in clause (2) of the definition thereof, the 35th trading day immediately following the effective date of such make-whole fundamental change) (such period, the "make-whole fundamental change period").

For the avoidance of doubt, if we elect to redeem less than all of the outstanding notes, then holders of the notes not called for redemption will not be entitled to an increased conversion rate for such notes as described in this section on account of the redemption.

Table of Contents

Upon surrender of notes for conversion in connection with a make-whole fundamental change or during a redemption period, we will deliver shares of our common stock, including the additional shares, as described under "— Conversion Rights — Settlement upon Conversion," but subject to the provisions described under "— Conversion Rights — Special Settlement Provisions in Connection with a Make-Whole Fundamental Change or Redemption Period." However, if the consideration for our common stock in any make-whole fundamental change described in clause (2) of the definition of fundamental change is composed entirely of cash, for any conversion of notes following the effective date of such make-whole fundamental change, the conversion obligation will be calculated based solely on the "stock price" (as defined below) for the transaction and will be deemed to be an amount of cash per $1,000 principal amount of converted notes equal to the conversion rate (including any increase to reflect the additional shares as described in this section),multiplied by such stock price. We will notify the trustee, the conversion agent (if other than the trustee) and holders of the effective date of any make-whole fundamental change no later than five business days after such effective date.

The amount, if any, by which the conversion rate will be increased will be determined by reference to the table below, based on the date on which the make-whole fundamental change occurs or becomes effective (the "effective date") or the redemption notice date, as applicable, and the price (the "stock price") paid (or deemed to be paid) per share of our common stock in the make-whole fundamental change or on the redemption notice date, as applicable. If the holders of our common stock receive in exchange for their common stock only cash in a make-whole fundamental change described in clause (2) of the definition of fundamental change, the stock price will be the cash amount paid per share. Otherwise, the stock price will be the average of the last reported sale prices of our common stock over the five consecutive trading day period ending on, and including, the trading day immediately preceding the effective date of the make-whole fundamental change or the redemption notice date, as the case may be. In the event that a conversion during a redemption period would also be deemed to be in connection with a make-whole fundamental change, a holder of the notes to be converted will be entitled to a single increase to the conversion rate with respect to the first to occur of the applicable redemption notice date or the effective date of the applicable make-whole fundamental change, and the later event will be deemed not to have occurred for purposes of this section.

The stock prices set forth in the column headings of the table below will be adjusted as of any date on which the conversion rate of the notes is otherwise adjusted. The adjusted stock prices will equal the stock prices immediately prior to such adjustment, multiplied by a fraction, the numerator of which is the conversion rate immediately prior to the adjustment giving rise to the stock price adjustment and the denominator of which is the conversion rate as so adjusted. The amounts by which the conversion rate will be increased as set forth in the table below will be adjusted in the same manner and at the same time as the conversion rate as set forth under "— Conversion Rights — Conversion Rate Adjustments."

The following table sets forth the amount, if any, by which the conversion rate will be increased per $1,000 principal amount of notes for each stock price and effective date or redemption notice date set forth below:

Table of Contents

The exact stock prices and effective dates or redemption notice dates may not be set forth in the table above, in which case:

§

if the stock price is between two stock prices in the table or the effective date or redemption notice date, as the case may be, is between two effective dates or redemption notice dates, as applicable, in the table, the amount by which the conversion rate will be increased will be determined by a straight-line interpolation between the amount of the conversion rate increase set forth for the higher and lower stock prices and the earlier and later effective dates or redemption notice dates, as applicable, based on a 365-day year;



§

if the stock price is greater than $20.00 per share (subject to adjustment in the same manner as the stock prices set forth in the column headings of the table above), the conversion rate will not be increased; and



§

if the stock price is less than $1.10 per share (subject to adjustment in the same manner as the stock prices set forth in the column headings of the table above), the conversion rate will not be increased.

Notwithstanding the foregoing, in no event will the conversion rate per $1,000 principal amount of notes exceed 909.0909 shares of common stock in the event of a make-whole fundamental change or notice of redemption, subject to adjustment in the same manner as the conversion rate as set forth under "— Conversion Rights — Conversion Rate Adjustments."

Our obligation to increase the conversion rate for notes converted in connection with a make-whole fundamental change or during a redemption period could be considered a penalty, in which case the enforceability thereof would be subject to general principles of reasonableness and equitable remedies.

Special Settlement Provisions in Connection with a Make-Whole Fundamental Change or Redemption Period

If a note is to be converted in connection with a make-whole fundamental change or during a redemption period, then we will settle such conversion based on a conversion rate that reflects the additional shares added thereto pursuant to the provisions described under "— Conversion Rights — Increase in Conversion Rate upon Conversion upon a Make- whole Fundamental Change or during a Redemption Period" section. However, in order to comply with Section 713 of the NYSE American LLC Company Guide that limit the number of shares we may deliver upon conversion of the notes unless we first obtain the approval of our stockholders (the "requisite stockholder approval") in accordance with the rules of the NYSE American, we may be required to partially cash settle conversions made in connection with a make-whole fundamental change or during a redemption period. Accordingly, if we have not obtained the requisite stockholder approval as of the effective date of a make-whole fundamental change or a redemption notice date, as applicable, then we will settle the conversion of a note made in connection with such make-whole fundamental change or during a redemption period as follows:

§

we will settle such conversion in the manner described above under the caption "Conversion Rights — Settlement upon Conversion", including such additional shares delivered pursuant to the caption entitled "Increase in Conversion Rate upon Conversion upon a Make- whole Fundamental Change or during a Redemption Period"; provided that we will not be required to deliver a number of shares of common stock per $1,000 principal amount greater than 775.1937, subject to adjustment in the same manner as the conversion rate as set forth under "— Conversion Rights — Conversion Rate Adjustments" (such number of shares, the "maximum share settled make whole shares"; and the excess of the number of shares that would have been delivered over the maximum share settled make whole shares, the "cash settled make whole shares"); and



§

in addition, we will pay with respect to the cash settled make whole shares, no later than the second business day after the conversion date for such conversion, an amount per $1,000 principal amount of such note to be converted equal to the product of the number of cash settled make whole shares and the stock price applicable to such make-whole fundamental change or redemption notice, as applicable.

Table of Contents

Notwithstanding anything to the contrary described above, if the consideration for our common stock in any make-whole fundamental change described in clause (2) of the definition of fundamental change is comprised entirely of cash, then we will settle the conversion of any note following the effective date of such make-whole fundamental change by delivering, on or before the second business day after the conversion date for such conversion, an amount of cash, per $1,000 principal amount of such note to be converted, equal to the product of (i) the stock price for such make-whole fundamental change; and (ii) the applicable conversion rate (including any adjustment as described in this section).

We will notify holders, in the notice of the make-whole fundamental change or redemption notice, as applicable, whether we have obtained the requisite stockholder approval.

Fundamental Change Permits Holders to Require Us to Repurchase Notes

If a "fundamental change" (as defined below in this section) occurs at any time prior to the maturity date, holders will have the right, at their option, to require us to repurchase for cash all of their notes, or any portion of the principal amount thereof that is equal to $1,000 or an integral multiple of $1,000. The fundamental change repurchase date will be a date specified by us that is not less than 20 or more than 35 business days following the date of our fundamental change notice as described below.

The fundamental change repurchase price we are required to pay will be equal to 100% of the principal amount of the notes to be repurchased,plus accrued and unpaid interest to, but excluding, the fundamental change repurchase date (unless the fundamental change repurchase date falls after a regular record date but on or prior to the interest payment date to which such regular record date relates, in which case we will instead pay the full amount of accrued and unpaid interest (to, but not including, such interest payment date) to the holder of record on such regular record date, and the fundamental change repurchase price will be equal to 100% of the principal amount of the notes to be repurchased).

A "fundamental change" will be deemed to have occurred at the time after the notes are originally issued if any of the following occurs:

(1)

a "person" or "group" within the meaning of Section 13(d) of the Exchange Act, other than us, our wholly owned subsidiaries and our and their employee benefit plans, files a Schedule TO (or any successor schedule, form or report) or any schedule, form or report under the Exchange Act that discloses that such person or group has become the direct or indirect "beneficial owner," as defined in Rule 13d-3 under the Exchange Act, of our common stock representing more than 50% of the voting power of our common stock, unless such beneficial ownership arises solely as a result of a revocable proxy delivered in response to a public proxy or consent solicitation made pursuant to the applicable rules and regulations under the Exchange Act;provided that no person or group shall be deemed to be the beneficial owner of any securities tendered pursuant to a tender or exchange offer made by or on behalf of such person or group until such tendered securities are accepted for purchase or exchange under such offer;



(2)

the consummation of (A) any recapitalization, reclassification or change of our common stock (other than changes resulting from a subdivision or combination or solely a change in par value) as a result of which our common stock would be converted into, or exchanged for, stock, other securities, other property or assets; (B) any share exchange, consolidation or merger of us pursuant to which our common stock will be converted into cash, securities or other property or assets; or (C) any sale, lease or other transfer in one transaction or a series of transactions of all or substantially all of the consolidated assets of us and our subsidiaries, taken as a whole, to any person other than one or more of our direct or indirect wholly owned subsidiaries;provided,however, that a transaction described in clauses (A) or (B) in which the holders of all classes of our common equity immediately prior to such transaction own, directly or indirectly, more than 50% of all classes of common equity of the continuing or surviving company or transferee or the parent

Table of Contents

thereof immediately after such transaction in substantially the same proportions (relative to each other) as such ownership immediately prior to such transaction shall not be a fundamental change pursuant to this clause (2);

(3)

our stockholders approve any plan or proposal for our liquidation or dissolution; or



(4)

our common stock (or other common stock, ordinary shares, American depositary receipts or other common equity interests underlying the notes) ceases to be listed or quoted on any of the NYSE American, The New York Stock Exchange, The Nasdaq Global Select Market, The Nasdaq Global Market or The Nasdaq Capital Market (or any of their respective successors).

A transaction or transactions described in clause (1) or clause (2) above will not constitute a fundamental change, however, if at least 90% of the consideration received or to be received by our common stockholders, excluding cash payments for fractional shares and cash payments made pursuant to dissenters' appraisal rights, in connection with such transaction or transactions consists of shares of common stock, ordinary shares, American depositary receipts or other common equity interests, in each case, that are listed or quoted on any of the NYSE American, The New York Stock Exchange, The Nasdaq Global Select Market, The Nasdaq Global Market or The Nasdaq Capital Market (or any of their respective successors) or will be so listed or quoted when issued or exchanged in connection with such transaction or transactions and as a result of such transaction or transactions such consideration becomes reference property for the notes, excluding cash payments for fractional shares and cash payments made pursuant to dissenters' appraisal rights (subject to the provisions set forth above under "— Conversion Rights — Settlement upon Conversion").

Any event, transaction or series of related transactions that constitute a fundamental change under both clause (1) and clause (2) above (determined without regard to the proviso in clause (2) above) will be deemed to be a fundamental change solely under clause (2) above.

If any transaction in which our common stock is replaced by the securities of another entity occurs, following completion of any related make-whole fundamental change period (or, in the case of a transaction that would have been a fundamental change or a make-whole fundamental change but for the immediately preceding paragraph, following the effective date of such transaction), references to us in the definition of "fundamental change" above shall instead be references to such other entity.

On or before the 20th business day after the occurrence of a fundamental change, we will provide to all holders of the notes, the trustee, the conversion agent (if other than the trustee) and paying agent (if other than the trustee) a notice of the occurrence of the fundamental change and of the resulting repurchase right. Such notice shall state, among other things:

§

the events causing a fundamental change;



§

the effective date of the fundamental change;



§

the last date on which a holder may exercise the repurchase right;



§

the fundamental change repurchase price;



§

the fundamental change repurchase date;



§

the name and address of the paying agent and the conversion agent, if applicable;



§

if applicable, the conversion rate and any adjustments to the conversion rate;



§

that the notes with respect to which a fundamental change repurchase notice has been delivered by a holder may be converted only if the holder withdraws the fundamental change repurchase notice in accordance with the terms of the indenture; and



§

the procedures that holders must follow to require us to repurchase their notes.

If notes are held in certificated form, to exercise the fundamental change repurchase right, holders of certificated notes must deliver, prior to the close of business on the business day immediately preceding the

Table of Contents

fundamental change repurchase date, the notes to be repurchased, duly endorsed for transfer, together with a written repurchase notice, to the paying agent. Each repurchase notice must state:

§

if certificated, the certificate numbers of your notes to be delivered for repurchase;



§

the portion of the principal amount of notes to be repurchased, which must be $1,000 or an integral multiple thereof; and



§

that the notes are to be repurchased by us pursuant to the applicable provisions of the notes and the indenture.

If the notes are not in certificated form, such repurchase notice must comply with applicable DTC procedures.

Holders of certificated notes may withdraw any repurchase notice (in whole or in part) by a written notice of withdrawal delivered to the paying agent prior to the close of business on the business day immediately preceding the fundamental change repurchase date. The notice of withdrawal shall state:

§

the principal amount of the withdrawn notes, which must be $1,000 aggregate principal amount or an integral multiple thereof;



§

if certificated notes have been issued, the certificate numbers of the withdrawn notes; and



§

the principal amount, if any, which remains subject to the repurchase notice, which must be $1,000 aggregate principal amount or an integral multiple thereof.

If the notes are not in certificated form, such notice of withdrawal must comply with applicable DTC procedures.

We will be required to repurchase the notes on the fundamental change repurchase date, subject to postponement to comply with applicable law. Holders who have exercised the repurchase right will receive payment of the fundamental change repurchase price on the later of (i) the fundamental change repurchase date and (ii) the time of book-entry transfer or the delivery of the notes. If the paying agent holds money sufficient to pay the fundamental change repurchase price of the notes on the fundamental change repurchase date, then, with respect to the notes that have been properly surrendered for repurchase and have not been validly withdrawn:

§

the notes will cease to be outstanding and interest will cease to accrue (whether or not book-entry transfer of the notes is made or whether or not the notes are delivered to the paying agent); and



§

all other rights of the holder will terminate (other than the right to receive the fundamental change repurchase price).

In connection with any repurchase offer pursuant to a fundamental change repurchase notice, we will, if required:

§

comply with the tender offer rules under the Exchange Act that may then be applicable;



§

file a Schedule TO or any other required schedule under the Exchange Act; and



§

otherwise comply in all material respects with all federal and state securities laws in connection with any offer by us to repurchase the notes;

in each case, so as to permit the rights and obligations under this "— Fundamental Change Permits Holders to Require Us to Repurchase Notes" to be exercised in the time and in the manner specified in the indenture.

No notes may be repurchased by us on any date at the option of holders upon a fundamental change if the principal amount of the notes has been accelerated, and such acceleration has not been rescinded, on or prior to such date (except in the case of an acceleration resulting from a default by us in the payment of the fundamental change repurchase price with respect to such notes).

Table of Contents

The repurchase rights of the holders upon a fundamental change could discourage a potential acquirer of us. The fundamental change repurchase feature, however, is not the result of management's knowledge of any specific effort to obtain control of us by any means or part of a plan by management to adopt a series of anti-takeover provisions.

Notwithstanding anything to the contrary in the foregoing, we will not be required to repurchase or make an offer to repurchase the notes upon a fundamental change if a third party makes such an offer in the same manner, at the same time and otherwise in compliance with the requirements for an offer made by us as set forth in the indenture and such third party purchases all notes properly surrendered and not validly withdrawn under its offer in the same manner, at the same time and otherwise in compliance with the requirements for an offer made by us as set forth in the indenture.

To the extent that the provisions of any securities laws or regulations conflict with the provisions of the indenture relating to our obligations to repurchase the notes upon a fundamental change, we will comply with the applicable securities laws and regulations and will not be deemed to have breached our obligations under such provisions of the indenture by virtue of such conflict.

The term fundamental change is limited to specified transactions and may not include other events that might adversely affect our financial condition. In addition, the requirement that we offer to repurchase the notes upon a fundamental change may not protect holders in the event of a highly leveraged transaction, reorganization, merger or similar transaction involving us.

Furthermore, holders may not be entitled to require us to repurchase their notes upon a fundamental change or entitled to an increase in the conversion rate upon conversion as described under "— Conversion Rights — Increase in Conversion Rate upon Conversion upon a Make-Whole Fundamental Change or during a Redemption Period" in circumstances involving a significant change in the composition of our board, unless such change is in connection with a fundamental change or make-whole fundamental change, as the case may be, as described herein.

The definition of fundamental change includes a phrase relating to the sale, lease or other transfer of "all or substantially all" of the consolidated assets of us and our subsidiaries, taken as a whole. There is no precise, established definition of the phrase "substantially all" under applicable law. Accordingly, the ability of a holder of the notes to require us to repurchase its notes as a result of the sale, lease or other transfer of less than all of the consolidated assets of us and our subsidiaries, taken as a whole may be uncertain.

If a fundamental change were to occur, we may not have enough funds to pay the fundamental change repurchase price. Our ability to repurchase the notes for cash may be limited by restrictions on our ability to obtain funds for such repurchase through dividends from our subsidiaries, the terms of our then existing borrowing arrangements or otherwise. See "Risk Factors — Risks Related to the Notes." The occurrence of a fundamental change could cause an event of default under, or be prohibited or limited by, the terms of existing or future senior debt.

We may not have the ability to raise the funds necessary to repurchase the notes for cash upon a fundamental change, and our future debt may contain limitations on our ability to repurchase the notes. If we fail to repurchase the notes when required following a fundamental change, we will be in default under the indenture. Any such default may, in turn, cause a default under existing or future senior debt. In addition, we have, and may in the future incur, other indebtedness with similar change in control provisions permitting our holders to accelerate or to require us to repurchase our indebtedness upon the occurrence of similar events or on some specific dates.

The amount of Disqualified Stock deemed to be outstanding at any time for purposes of the indenture will be the maximum amount that the Company or any and its Restricted Subsidiaries may become obligated to pay upon the maturity of, or pursuant to any mandatory repurchase or redemption provisions of, such Disqualified Stock exclusive of accrued dividends (other than the accretion, accumulation or payment-in-kind of dividends).

Asset Sales

The indenture provides that the Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, consummate an Asset Sale unless:

(1)

the Company or such Restricted Subsidiary receives consideration at the time of such Asset Sale at least equal to the Fair Market Value of the assets subject to such Asset Sale; and

The indenture provides that the Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, effect any Product Intellectual Property Sale or Exclusive Product License to any Unrestricted Subsidiary or other subsidiary that is not a subsidiary guarantor.

The Net Proceeds (or any portion thereof) (as defined herein) from Asset Sales may be applied by the Company or a Restricted Subsidiary (A) within 90 days of receipt thereof, to repay, prepay, repurchase, redeem, legally defease or otherwise retire the Credit Facilities (as defined herein) or any other Indebtedness of the Company or any Restricted Subsidiary secured by a Lien on assets of the Company or any Restricted Subsidiary of the Company (excluding, in any such case, any Indebtedness owed to the Company or an Affiliate of the Company) (for purposes of this "Asset Sales" covenant, the "Senior Obligations") or (B) within 360 days of receipt thereof, if the Asset Sale is not a Product Intellectual Property Sale and solely with respect to the percentage of the Net Proceeds set forth in the "Company Retention" column in the table below, to reinvest in Additional Assets or R&D Expenditures (including by means of an Investment in Additional Assets or R&D Expenditures by a Restricted Subsidiary with Net Proceeds received by the Company or another Restricted Subsidiary), and in the case of either clause (A) or (B), to the extent not so applied shall constitute "Excess Proceeds."

Pending application of Net Proceeds pursuant to this covenant, such Net Proceeds shall, to the extent not inconsistent with the terms of the Senior Obligations, be invested in Cash Equivalents or applied to temporarily reduce revolving credit indebtedness. If the Asset Sale is not a Product Intellectual Property Sale and solely with respect to the percentage of the Net Proceeds set forth in the "Company Retention" column in the table above, any Net Proceeds that are not segregated from the general funds of the Company for investment in identified Additional Assets or R&D Expenditures in respect of a project that shall have been commenced, and/or for which binding contractual commitments have been entered into, prior to the end of such 360-day period shall constitute "Excess Proceeds";provided,however, that the amount of any Net Proceeds that ceases to be so segregated as contemplated above and any unapplied Net Proceeds that is segregated in respect of a project that is abandoned or completed shall also constitute "Excess Proceeds" at the time any such Net Proceeds ceases to be so segregated or at the time the relevant project is so abandoned or completed, as applicable;provided further, however, that the amount of any Net Proceeds that continues to be segregated for investment and that is not actually reinvested within 18 months from the date of the receipt of such Net Proceeds shall also constitute "Excess Proceeds."

To the extent permitted under the Credit Agreement, when the aggregate amount of Excess Proceeds exceeds $7.5 million, the Company will be required to make an offer to purchase (the "Asset Sales Prepayment Offer") the notes which offer shall be in the amount of the Allocable Excess Proceeds (as defined herein), on a pro rata basis according to principal amount at maturity, at a purchase price equal to 100% of the principal amount thereof, plus accrued and unpaid interest, if any, to the purchase date (subject to the right of holders of record on the relevant record date to receive interest due on the relevant

Table of Contents

interest payment date), in accordance with the procedures (including prorating in the event of oversubscription) set forth in the indenture. To the extent that any portion of the amount of Net Proceeds remains after compliance with the preceding sentence andprovided that all holders of notes have been given the opportunity to tender their notes for purchase in accordance with the indenture, the Company or such Restricted Subsidiary may use such remaining amount for any purpose permitted by the indenture and the amount of Excess Proceeds will be reset to zero.

The term "Allocable Excess Proceeds" will mean the product of:

(1)

the Excess Proceeds; and



(2)

a fraction,



(i)

the numerator of which is the aggregate principal amount of the notes outstanding on the date of the Asset Sales Prepayment Offer; and



(ii)

the denominator of which is the sum of the aggregate principal amount of the notes outstanding on the date of the Asset Sales Prepayment Offer and the aggregate principal amount of other Indebtedness of the Company outstanding on the date of the Asset Sales Prepayment Offer that is pari passu in right of payment with the notes and subject to terms and conditions in respect of Asset Sales similar in all material respects to this covenant and requiring the Company to make an offer to purchase such Indebtedness or otherwise repay such Indebtedness at substantially the same time as the Asset Sales Prepayment Offer.

Within twenty business days after the Company is obligated to make an Asset Sales Prepayment Offer as described in the preceding paragraph, the Company will send a written notice, by first-class mail or electronically, to the holders of the notes, accompanied by such information regarding the Company and its Subsidiaries as the Company in good faith believes will enable such holders to make an informed decision with respect to such Asset Sales Prepayment Offer. Such notice shall state, among other things, the purchase price and the purchase date, which shall be, subject to any contrary requirements of applicable law, a business day no earlier than 20 days nor later than 30 business days from the date such notice is mailed. Nothing shall prevent the Company from conducting an Asset Sales Prepayment Offer earlier than as set forth in this paragraph. Upon completion of each Asset Sale Prepayment Offer, the amount of Excess Proceeds shall be reset to zero.

In connection with any Asset Sales Prepayment Offer pursuant to this "Asset Sales" covenant, we will, if required:

§

comply with the tender offer rules under the Exchange Act that may then be applicable;



§

file a Schedule TO or any other required schedule under the Exchange Act; and



§

otherwise comply in all material respects with all federal and state securities laws in connection with any offer by us to repurchase the notes;

in each case, so as to permit the rights and obligations under this "— Asset Sales" covenant to be exercised in the time and in the manner specified in the indenture. To the extent that the provisions of any securities laws or regulations conflict with provisions of this covenant, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under this covenant by virtue thereof.

deliver to the trustee an Officer's Certificate and an Opinion of Counsel, each certifying that such supplemental indenture and such supplement to the Registration Rights Agreement, if applicable, has been duly authorized, executed and delivered by such Restricted Subsidiary and constitutes a valid and legally binding and enforceable obligation of such Restricted Subsidiary, subject to customary exceptions.

Thereafter, such Restricted Subsidiary shall be a subsidiary guarantor for all purposes.

Designation of Restricted and Unrestricted Subsidiaries

As of the Issue Date and the date hereof, all of the Subsidiaries of the Company were and are Restricted Subsidiaries. The indenture provides that our board of directors or a committee thereof will be able, at any time after the Issue Date, to designate any Restricted Subsidiary to be an Unrestricted Subsidiary;provided, that immediately before and after such designation, no Default or Event of Default shall have occurred and be continuing. If a Restricted Subsidiary is designated as an Unrestricted Subsidiary, the aggregate Fair Market Value of all outstanding Investments owned by the Company and its Restricted Subsidiaries in the Restricted Subsidiary designated as an Unrestricted Subsidiary will be deemed to be an Investment made as of the time of the designation and will reduce the amount available for Restricted Payments permitted under the "— Covenants — Restricted Payments" covenant. That designation will only be permitted if the Investment would be permitted at that time and if such Restricted Subsidiary otherwise meets the definition of an "Unrestricted Subsidiary."

Any designation of a Subsidiary of the Company as an Unrestricted Subsidiary will be evidenced to the trustee by filing with the trustee a certified copy of a resolution of our board of directors or a committee thereof giving effect to such designation and an Officer's Certificate certifying that such designation complied with the preceding conditions and was permitted by the "— Covenants — Restricted Payments" covenant. If, at any time, any Unrestricted Subsidiary would fail to meet the preceding requirements as an Unrestricted Subsidiary, it will thereafter cease to be an Unrestricted Subsidiary and any Indebtedness of such Unrestricted Subsidiary will be deemed to be incurred by a Restricted Subsidiary of the Company as of such date and, if such Indebtedness is not permitted to be incurred as of such date under the "— Covenants — Incurrence of Indebtedness and Issuance of Preferred Stock" covenant, the Company will be in Default of such covenant. Our board of directors or a committee thereof may at any time designate any Unrestricted Subsidiary to be a Restricted Subsidiary of the Company;provided that such designation will be deemed to be an incurrence of Indebtedness by a Restricted Subsidiary of the Company of any outstanding Indebtedness of such Unrestricted Subsidiary and the creation, incurrence, assumption or otherwise causing to exist any Lien of such Unrestricted Subsidiary, and such designation will only be permitted if (1) such Indebtedness is permitted under the "— Covenants — Incurrence of Indebtedness and Issuance of Preferred Stock" covenant, calculated on a pro forma basis as if such designation had occurred at the beginning of the relevant four-quarter period; (2) such Lien is permitted; and (3) no Default or Event of Default would be in existence following such designation.

Limitation on Issuance of Capital Stock

The indenture provides that no subsidiary guarantor may issue any Capital Stock of such subsidiary guarantor (including by way of sales of treasury stock or the issuance of any debt security that is convertible into, or exchangeable for, Capital Stock of such subsidiary guarantor) to any Person other than (i) to the Company or any other subsidiary guarantor, (ii) in connection with the transfer of all of the Capital Stock of such subsidiary guarantor otherwise permitted under the indenture, or (iii) the issuance of director's qualifying shares or other nominal shares required by law to be held by a Person other than the Company or a subsidiary guarantor.

Consolidation, Merger and Sale of Assets

The indenture provides that we shall not consolidate with or merge with or into, or sell, convey, transfer or lease all or substantially all of the consolidated properties and assets of us and our direct or indirect subsidiaries, taken as a whole, to another person, unless (i) the resulting, surviving or transferee person (if not us) is a corporation organized and existing under the laws of the United States of America, any State thereof or the District of Columbia, and such corporation (if not us) expressly assumes by executing and delivering a supplemental indenture and any other agreements (including, without limitation, any registration rights agreement, if applicable) all of our obligations under the notes and the indenture; and (ii) immediately after giving effect to such transaction, no default or event of default has occurred and is continuing under the indenture. Upon any such consolidation, merger or sale, conveyance, transfer or lease, the resulting, surviving or transferee person (if not us) shall succeed to, and may exercise every right and power of, ours under the notes and the indenture, and we shall be discharged from our obligations under the notes and the indenture except in the case of any such lease.

In addition, the indenture provides that a subsidiary guarantor shall not consolidate with or merge with or into, or sell, convey, transfer or lease all or substantially all of its properties and assets to another person (other than us or another subsidiary guarantor), unless (i) the resulting, surviving or transferee person (if not such subsidiary guarantor, us or another subsidiary guarantor) expressly assumes by executing and delivering a supplemental indenture and any other agreements (including, without limitation, any registration rights agreement, if applicable) all of that subsidiary guarantor's obligations under the notes and the indenture; and (ii) immediately after giving effect to such transaction, no default or event of default has occurred and is continuing under the indenture. Upon any such consolidation, merger or sale, conveyance, transfer or lease, the resulting, surviving or transferee person (if not us or another subsidiary guarantor) shall succeed to, and may exercise every right and power of, that subsidiary guarantor under the notes and the indenture, and that subsidiary guarantor shall be discharged from its obligations under the notes and the indenture except in the case of any such lease.

Notwithstanding the foregoing, the foregoing shall not apply to:

§

any sale, conveyance, transfer or lease of all or substantially all of the assets of that subsidiary guarantor (including by way of merger or consolidation) to a person that is not (either before or after giving effect to such transaction) us or one of our restricted subsidiaries if the sale or other disposition does not violate the "Asset Sales" covenant in the indenture; and



§

any merger or consolidation of any subsidiary guarantor with a Person that is not (either before or after giving effect to such transaction) us or one of our restricted subsidiaries, if the sale or other disposition does not violate the "Asset Sales" covenant in the indenture and that subsidiary guarantor ceases to be our restricted subsidiary as a result of the sale or other disposition.

Although these types of transactions are permitted under the indenture, certain of the foregoing transactions could constitute a fundamental change permitting each holder to require us to repurchase the notes of such holder as described above.

This covenant includes a phrase relating to the sale, conveyance, transfer and lease of "all or substantially all" properties and assets. There is no precise, established definition of the phrase "all or substantially all" under applicable law. Accordingly, whether a sale, conveyance, transfer or lease of less than all of the relevant properties and assets constitutes a sale or other disposition of "all or substantially all" may be uncertain.

Events of Default

Each of the following is an event of default with respect to the notes:

(1)

default in any payment of interest on any note when due and payable and the default continues for a period of 30 days;

Table of Contents

(2)

default in the payment of principal of any note when due and payable at its stated maturity, upon redemption, upon any required repurchase, upon declaration of acceleration or otherwise;



(3)

our failure to comply with our obligation to convert the notes in accordance with the indenture upon exercise of a holder's conversion right;



(4)

our failure to give a fundamental change notice as described under "— Fundamental Change Permits Holders to Require Us to Repurchase Notes" or notice of a make-whole fundamental change as described under "Increase in Conversion Rate Upon Conversion Upon a Make-Whole Fundamental Change or during a Redemption Period," in each case, when due and such failure continues for three (3) business days after the due date for such notice;



(5)

our failure to comply with our obligations under "— Consolidation, Merger and Sale of Assets;"



(6)

our failure for 60 days after written notice from the trustee or the holders of at least 25% in principal amount of the notes then outstanding has been received to comply with any of our other agreements contained in the notes or indenture;



(7)

default by us or any of our significant subsidiaries with respect to any mortgage, agreement or other instrument under which there may be outstanding, or by which there may be secured or evidenced, any indebtedness for money borrowed in excess of $10,000,000 (or its foreign currency equivalent) in the aggregate of ours and/or of any such significant subsidiary, whether such indebtedness now exists or shall hereafter be created (i) resulting in such indebtedness becoming or being declared due and payable prior to its stated maturity or (ii) constituting a failure to pay the principal or interest of any such debt when due and payable (after the expiration of all applicable grace periods) at its stated maturity, upon redemption, upon required repurchase, upon declaration of acceleration or otherwise, and in the cases of clauses (i) and (ii), such acceleration shall not have been rescinded or annulled or such failure to pay or default shall not have been cured or waived, or such indebtedness shall not have been paid or discharged, as the case may be, within 30 days after written notice to us by the trustee or to us and the trustee by holders of at least 25% in aggregate principal amount of the notes then outstanding in accordance with the indenture;



(8)

certain events of bankruptcy, insolvency, or reorganization of us or any of our significant subsidiaries;



(9)

(10)

except as permitted by the indenture, any subsidiary guarantee shall be held in any judicial proceeding to be unenforceable or invalid or shall cease for any reason to be in full force and effect, or any subsidiary guarantor, or any person acting on its behalf, shall deny or disaffirm its obligation under the subsidiary guarantee.

A "significant subsidiary" is a subsidiary that is a "significant subsidiary," as defined in Article 1, Rule 1-02 of Regulation S-X promulgated by the SEC as in effect on the date of the indenture provided that, in the case of a subsidiary that meets the criteria of clause (3) of the definition thereof but not clause (1) or (2) thereof, such subsidiary shall not be deemed to be a significant subsidiary unless the subsidiary's income from continuing operations before income taxes, extraordinary items and cumulative

Table of Contents

effect of a change in accounting principle exclusive of amounts attributable to any non-controlling interests for the last completed fiscal year prior to the date of such determination exceeds $5,000,000.

If an event of default occurs and is continuing, the trustee by notice to us, or the holders of at least 25% in principal amount of the outstanding notes by notice to us and the trustee, may, and the trustee at the request of such holders shall, declare 100% of the principal amount of and accrued and unpaid interest, if any, on all outstanding notes to be due and payable. Upon such a declaration of acceleration, such principal and accrued and unpaid interest, if any, will be due and payable immediately. In case of any event of default described in clause (8) above with respect to us, 100% of the principal of and accrued and unpaid interest on the notes will automatically become due and payable.

Notwithstanding the foregoing, the indenture provides that, to the extent we elect, the sole remedy for an event of default under the indenture relating to (i) our failure to file with the trustee pursuant to Section 314(a)(1) of the Trust Indenture Act any documents or reports that we are required to file with the SEC pursuant to Section 13 or 15(d) of the Exchange Act or (ii) our failure to comply with our obligations as set forth under "— Reports" below, will (x) for the first 180 days after the occurrence of such an event of default (beginning on, and including, the date on which such an event of default first occurs), consist exclusively of the right to receive additional interest on the notes at a rate equal to 0.25% per annum of the principal amount of notes outstanding for each day during such 180-day period on which such event of default is continuing and (y) for the period from, and including, the 181st day after the occurrence of such an event of default to, and including, the 365th day after the occurrence of such an event of default, consist exclusively of the right to receive additional interest on the notes at a rate equal to 0.50% per annum of the principal amount of notes outstanding for each day during such additional 185-day period on which such event of default is continuing. In no event will the additional interest described in this paragraph accrue at a rate in excess of 0.25% per annum during the initial 180-day period or 0.50% per annum during the subsequent 185-day period pursuant to the indenture, regardless of the number of events or circumstances giving rise to the requirement to pay such additional interest (in addition to any additional interest that may accrue as a result of our failure to comply with our obligations as described under "— Rule 144 Resales and Registration Rights — Registration Rights"). In no event will additional interest payable at our election for failure to comply with our reporting obligations pursuant to this "— Events of Default" (together with any additional interest that may accrue as a result of our failure to comply with our obligations as described "— Rule 144 Resales and Registration Rights — Registration Rights") accrue at a rate in excess of 0.50% per annum pursuant to the indenture, regardless of the number of events or circumstances giving rise to the requirement to pay such additional interest.

If we so elect, such additional interest will be payable in the same manner and on the same dates as the stated interest payable on the notes. On the 366th day after such event of default (if the event of default relating to the reporting obligations is not cured or waived prior to such 366th day), the notes will be subject to acceleration as provided above. The provisions of the indenture described in this paragraph will not affect the rights of holders of notes in the event of the occurrence of any other event of default. In the event we do not elect to pay the additional interest following an event of default in accordance with this paragraph or we elected to make such payment but do not pay the additional interest when due, the notes will be immediately subject to acceleration as provided above.

In order to elect to pay the additional interest as the sole remedy during the first 365 days after the occurrence of an event of default relating to the failure to comply with the reporting obligations in accordance with the immediately preceding two paragraphs, we must notify all holders of the notes, the trustee and the paying agent in writing of such election on or before the close of business on the date on which such event of default first occurs. Upon our failure to timely give such notice, the notes will be immediately subject to acceleration as provided above.

The holders of a majority in principal amount of the outstanding notes may waive all past defaults (except with respect to nonpayment of principal or interest or with respect to the failure to deliver the consideration

Table of Contents

due upon conversion) and rescind any such acceleration with respect to the notes and its consequences if (i) rescission would not conflict with any judgment or decree of a court of competent jurisdiction and (ii) all existing events of default, other than the nonpayment of the principal of and interest on the notes that have become due solely by such declaration of acceleration, have been cured or waived.

Each holder shall have the right to receive payment or delivery, as the case may be, of:

§

the principal (including the redemption price and the fundamental change repurchase price, if applicable) of;



§

accrued and unpaid interest, if any, on; and



§

the consideration due upon conversion of,

its notes, on or after the respective due dates expressed or provided for in the indenture, or to institute suit for the enforcement of any such payment or delivery on or after the applicable due date, as the case may be.

Subject to the provisions of the indenture relating to the duties of the trustee, if an event of default occurs and is continuing, the trustee will be under no obligation to exercise any of the rights or powers under the indenture at the request or direction of any of the holders unless such holders have offered to the trustee indemnity or security reasonably satisfactory to the trustee in its reasonable judgment against any loss, liability, claim or expense. Except to enforce the right to receive payment of principal or interest when due, or the right to receive payment or delivery of the consideration due upon conversion, no holder may pursue any remedy with respect to the indenture or the notes unless:

(1)

such holder has previously given the trustee written notice that an event of default with respect to the notes is continuing;



(2)

holders of at least 25% in aggregate principal amount of the outstanding notes have requested the trustee to pursue the remedy;



(3)

such holders have offered the trustee security or indemnity reasonably satisfactory to the trustee in its reasonable judgment against any loss, liability, claim or expense;



(4)

the trustee has not complied with such request within 60 days after the receipt of the request and the offer of such security or indemnity; and



(5)

the holders of a majority in principal amount of the outstanding notes have not given the trustee a direction that, in the opinion of the trustee, is inconsistent with such request within such 60-day period.

Subject to certain restrictions, the holders of a majority in principal amount of the outstanding notes are given the right to direct the time, method and place of conducting any proceeding for any remedy available to the trustee or of exercising any trust or power conferred on the trustee.

The indenture provides that in the event an event of default has occurred and is continuing, the trustee will be required in the exercise of its powers to use the degree of care that a prudent person would use in the conduct of its own affairs. The trustee, however, may refuse to follow any direction that conflicts with law or the indenture or that the trustee determines is unduly prejudicial to the rights of any other holder or that would involve the trustee in personal liability. Prior to taking any action under the indenture, the trustee will be entitled to security or indemnification reasonably satisfactory to the trustee in its reasonable judgment against any loss, liability or expense caused by taking or not taking such action.

The indenture provides that if a default occurs and is continuing and is actually known to a responsible officer of the trustee, the trustee must send to each holder notice of the default within 90 days after it obtains such knowledge. Except in the case of a default in the payment of principal of or interest on any note or a default in the payment or delivery of the consideration due upon conversion, the trustee may

Table of Contents

withhold notice if and so long as it in good faith determines that withholding notice is in the interests of the holders. In addition, we are required to deliver to the trustee, within 120 days after the end of each fiscal year, a certificate indicating whether the signers thereof know of any event of default under the indenture that occurred during the previous year. We are also required to deliver to the trustee, within 30 days after obtaining knowledge of the occurrence thereof, written notice of any events which would constitute certain events of defaults, their status and what action we are taking or proposing to take in respect thereof;provided that we are not required to deliver such notice if such event of default has been cured.

Payments of the redemption price, the fundamental change repurchase price, principal and interest that are not made when due will accrue interest per annum at the then-applicable interest rate from the required payment date.

Modification and Amendment

Subject to certain exceptions, the indenture or the notes may be amended with the consent of the holders of at least a majority in principal amount of the notes then outstanding (including, without limitation, consents obtained in connection with a repurchase of, or tender or exchange offer for, notes) and, subject to certain exceptions, any past default or compliance with any provisions may be waived with the consent of the holders of a majority in principal amount of the notes then outstanding (including, without limitation, consents obtained in connection with a repurchase of, or tender or exchange offer for, notes). However, without the consent of each holder of an outstanding note affected, no amendment may, among other things:

(1)

reduce the principal amount of notes whose holders must consent to an amendment or waiver;



(2)

reduce the rate of or extend the stated time for payment of interest on any note;



(3)

reduce the principal of or extend the stated maturity of any note;



(4)

make any change that adversely affects the conversion rights of any notes other than as required by the indenture;

make any change in the amendment provisions that require each holder's consent or in the waiver provisions; or

(2)

provide for the assumption by a successor company of our obligations under the indenture and the notes;

(8)

(9)

[reserved];



(10)

comply with any requirement of the SEC in connection with the qualification of the indenture under the Trust Indenture Act;

(13)

Holders do not need to approve the particular form of any proposed amendment. It will be sufficient if such holders approve the substance of the proposed amendment. After an amendment under the indenture becomes effective, we are required to deliver to the holders a notice briefly describing such amendment. However, the failure to give such notice to all the holders, or any defect in the notice, will not impair or affect the validity of the amendment.

Discharge; Defeasance

We may satisfy and discharge our obligations under the notes and the indenture by delivering to the securities registrar for cancellation all outstanding notes or by depositing with the trustee or delivering to the holders, as applicable, after the notes have become due and payable, whether at maturity, at any redemption date, at any fundamental change repurchase date, upon conversion or otherwise, cash and/or (in the case of conversion) shares of common stock sufficient to pay all of the outstanding notes and paying all other sums payable under the indenture by us. Such discharge is subject to terms contained in the indenture.

In addition, we may elect, at our option, to have our obligations released with respect to the covenants described under "— Covenants — Asset Sales," "— Covenants — Restricted Payments," "— Covenants — Incurrence of Indebtedness and Issuance of Preferred Stock," "— Covenants — Liens," "— Covenants — Dividend and Other Payment Restrictions Affecting Restricted Subsidiaries," — Covenants "— Transactions with Affiliates," "— Covenants — Limitation on Issuance of Capital Stock" and "— Covenants — Future Subsidiary Guarantees" ("covenant defeasance") and any omission to comply with such obligation shall not constitute a default or an event of default with respect to the notes. In the event covenant defeasance occurs, certain events (not including non-payment, failure to comply with obligation to convert the notes, failure to give a fundamental change or make-whole fundamental change notice, failure to comply with the

Table of Contents

covenant described under "— Consolidation, Merger and Sale of Assets" and bankruptcy and insolvency events) described under "— Events of Default" will no longer constitute an event of default with respect to the notes. In addition, if we exercise our covenant defeasance option, each subsidiary guarantor will be released from all of its obligations with respect to its applicable guarantee.

To exercise covenant defeasance with respect to the notes:

(1)

we must irrevocably have deposited or caused to be deposited with the trustee as trust funds in trust for the purpose of making the following payments, specifically pledged as security for, and dedicated solely to the benefits of the holders: (A) money in an amount, or (B) U.S. government obligations, which through the scheduled payment of principal and interest in respect thereof in accordance with their terms will provide, not later than the due date of any payment, money in an amount or (C) a combination thereof, in each case sufficient without reinvestment, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the trustee, to pay and discharge, and which shall be applied by the trustee to pay and discharge, the entire indebtedness in respect of the principal of and premium, if any, and interest on such notes at maturity thereof, in accordance with the terms of the indenture and such notes;



(2)

no default or event of default with respect to the outstanding notes shall have occurred and be continuing at the time of such deposit after giving effect thereto;



(3)

such covenant defeasance shall not cause the trustee to have a conflicting interest within the meaning of the Trust Indenture Act of 1939, as amended (assuming all notes are in default within the meaning of such Act);



(4)

such covenant defeasance shall not result in a breach or violation of, or constitute a default under, any material agreement or material instrument (other than the indenture) to which we are a party or by which we are bound;



(5)

delivery of an opinion of counsel to the effect that beneficial owners of the notes will not recognize income, gain or loss for U.S. federal income tax purposes as a result of such deposit and defeasance and will be subject to U.S. federal income tax on the same amount and in the same manner and at the same times as would have been the case if such deposit and defeasance had not occurred; and



(6)

we shall have delivered to the trustee an officer's certificate and an opinion of counsel, each stating that all conditions precedent with respect to such covenant defeasance have been complied with.

The notes are not subject to legal defeasance.

Reports

The indenture provides that any annual or quarterly reports (on Form 10-K or Form 10-Q or any respective successor form) that we are required to file with the SEC pursuant to Section 13 or 15(d) of the Exchange Act (excluding any such information, documents or reports, or portions thereof, subject to confidential treatment and any correspondence with the SEC) must be filed by us with the trustee within 15 days after the same are required to be filed with the SEC (giving effect to any grace period provided by Rule 12b-25 or any successor rule under the Exchange Act). Documents filed by us with the SEC via the EDGAR system (or any successor thereto) will be deemed to be filed with the trustee as of the time such documents are filed via EDGAR (or any successor thereto), it being understood that the trustee shall not be responsible for determining whether such filings have been made. Delivery of reports, information and documents to the trustee under the indenture is for informational purposes only and the information and the trustee's receipt of the foregoing shall not constitute constructive notice of any information contained therein, or

Table of Contents

determinable from information contained therein including our compliance with any of its covenants thereunder (as to which the trustee is entitled to rely exclusively on an officer's certificate).

We will schedule a conference call to be held not more than 15 days following the release of each quarterly and annual report referred to in the preceding paragraph, but after the release of any "earnings release" corresponding to the period of such report, at which we will make available at least one member of our senior management to discuss the information contained in such report on such conference call. The indenture permits us to satisfy this obligation as part of our quarterly and annual earnings conference calls. We will notify holders about such call and provide them with call-in information concurrently with and in the same manner as each delivery of such reports.

If we have designated any subsidiaries as unrestricted subsidiaries, then our quarterly and annual financial information required by the second preceding paragraph will include a reasonably detailed presentation, either on the face of the financial statements or in the footnotes thereto, of the financial condition and results of operations of us and our restricted subsidiaries separate from the financial condition and results of operations of the our unrestricted subsidiaries.

Calculations in Respect of Notes

Except as otherwise provided above, we will be responsible for making all calculations called for under the notes. These calculations include, but are not limited to, determinations of the stock price, the last reported sale prices of our common stock, accrued interest payable on the notes and the conversion rate of the notes (including any adjustments thereof). We will make all these calculations in good faith and, absent manifest error, our calculations will be final and binding on holders of notes. We will provide a schedule of our calculations to each of the trustee and the conversion agent, and each of the trustee and the conversion agent is entitled to rely conclusively upon the accuracy of our calculations without independent verification. The trustee will forward our calculations to any holder of notes upon the written request of that holder.

Rule 144A Information

At any time we are not subject to Section 13 or Section 15(d) of the Exchange Act, we will, so long as any of the notes or any shares of our common stock issuable upon conversion thereof will, at such time, constitute "restricted securities" within the meaning of Rule 144(a)(3) under the Securities Act, promptly provide to the trustee and will, upon written request, provide to any holder, beneficial owner or prospective purchase of such notes or any shares of our common stock issuable upon conversion of such notes the information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act to facilitate the resale of such notes or shares of our common stock pursuant to Rule 144A under the Securities Act. We will take such further action as any holder or beneficial owner of such notes may reasonably request to the extent from time to time required to enable such holder or beneficial owner to sell such notes or shares of our common stock in accordance with Rule 144A under the Securities Act, as such rule may be amended from time to time.

Trustee

U.S. Bank National Association is the trustee, security registrar, paying agent and conversion agent. U.S. Bank National Association, in each of its capacities, including without limitation as trustee, security registrar, paying agent and conversion agent, assumes no responsibility for the accuracy or completeness of the information concerning us or our affiliates or any other party contained in this document or the related documents or for any failure by us or any other party to disclose events that may have occurred and may affect the significance or accuracy of such information.

The trustee is also the trustee under the indenture governing the 2023 notes. In addition, we maintain banking relationships in the ordinary course of business with the trustee and its affiliates.

Table of Contents

Governing Law

The indenture provides that it and the notes, and any claim, controversy or dispute arising under or related to the indenture or the notes, will be governed by and construed in accordance with the laws of the State of New York.

Rule 144 Resales and Registration Rights

General

You may resell your notes or shares of our common stock issued upon conversion of notes pursuant to an exemption from the registration requirements of the Securities Act and other applicable securities laws or pursuant to this resale registration statement.

Subject to the Rule 144(i) exception discussed below, in general under Rule 144 under the Securities Act ("Rule 144") as currently in effect, a person who acquired notes from us (or our affiliate) and who has beneficially owned notes or shares of our common stock issued upon conversion of the notes for at least one year is entitled to sell such notes or shares of our common stock without registration, but only if such person is not deemed to have been our affiliate at the time of, or at any time during three months immediately preceding, the sale. Furthermore, subject to the Rule 144(i) exception discussed below, under Rule 144, a person who acquired notes from us (or our affiliate) and who has beneficially owned notes or shares of our common stock issued upon conversion of the notes for at least six months is entitled to sell such notes or shares of our common stock without registration, so long as (i) such person is not deemed to have been our affiliate at the time of, or at any time during three months immediately preceding, the sale and (ii) we have filed all required reports under Section 13 or Section 15(d) of the Exchange Act, as applicable, during the twelve months preceding such sale (other than current reports on Form 8-K). Subject to the Rule 144(i) exception discussed below, if we are not current in filing our Exchange Act reports, a person who acquires from our affiliate notes or shares of our common stock issued upon conversion of the notes could be required to hold such notes or shares of our common stock for up to one year following such acquisition. If we are not current in filing our Exchange Act reports, a person who is our affiliate and who owns notes or shares of our common stock issued upon conversion of the notes could be required to hold such notes or shares of our common stock indefinitely.

We will use commercially reasonable efforts to prevent any of our "affiliates" (as defined in Rule 144) from acquiring any note.

Rule 144(i) Exception

Rule 144(i)(1) prohibits a stockholder or holder of notes from relying on Rule 144 if the issuer is now or at any time previously has been a "shell company" (as described in Rule 144(i)(1)(i)), unless the requirements of Rule 144(i)(2) are satisfied. Since we were previously a shell company described in Rule 144(i)(1)(i), but have subsequently ceased to be a shell company, Rule 144(i)(2) will permit the use of Rule 144 by our stockholders or holders of notes if the following requirements are satisfied at the time of the proposed sale in reliance on Rule 144:

§

we are subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act (i.e., required to file periodic reports with the SEC);



§

we have filed all reports and other materials required to be filed with the SEC for at least the preceding 12 months (or for such shorter period that we were required to file such reports and materials) other than Form 8-K reports; and



§

we have filed current "Form 10 information" with the SEC reflecting our status as an entity that is no longer an issuer described in Rule 144(i)(1)(i) (which we filed with the SEC on Form 8-K on December 10, 2015).

Registration Rights

We prepared this prospectus in connection with our obligations under the Registration Rights Agreement, which provides the selling securityholders with certain registration rights with respect to the resale of the notes, the subsidiary guarantees and the shares of common stock issuable upon conversion of the notes.

We will pay additional interest on any interest payment date to the holders of notes and the shares of common stock issued upon conversion of the notes if the resale documents are unavailable for periods in excess of those permitted. Such additional interest will accrue until the date prior to the day the default is cured at a rate per year equal to:

§

on the notes that are registrable securities (i) at an annual rate of 0.25% of the aggregate principal amount of such notes outstanding for the first 90 days and (ii) thereafter at an annual rate of 0.50% of the aggregate principal amount of such notes outstanding; and



§

on the shares of common stock that have been issued upon conversion of the notes and that are registrable securities (i) at an annual rate of 0.25% of the corresponding principal amount of notes that were so converted and (ii) thereafter at an annual rate equal to 0.50% of the corresponding principal amount of notes that were so converted.

Additional interest pursuant to the foregoing provisions will be payable in arrears on each interest payment date following accrual in the same manner as regular interest on the notes and will be in addition to any additional interest that may accrue at our election as the sole remedy relating to the failure to comply with our reporting obligations as described under "— Events of Default." In no event will additional interest payable at our election for failure to comply with our obligations pursuant to this "— Rule 144 Resales and Registration Rights — Registration Rights" (together with any additional interest that may accrue as a result of our failure to comply with our obligations as described under "— Events of Default") accrue at a rate in excess of 0.50% per annum pursuant to the indenture, regardless of the number of events or circumstances giving rise to the requirement to pay such additional interest.

Book-Entry, Settlement and Clearance

The Global Notes

The notes were initially issued in the form of one or more registered notes in global form, without interest coupons (the "global notes"). Each of the global notes was deposited with the trustee as custodian for DTC and registered in the name of Cede & Co., as nominee of DTC.

Ownership of beneficial interests in a global note is limited to persons who have accounts with DTC ("DTC participants") or persons who hold interests through DTC participants. We expect that under procedures established by DTC:

§

upon deposit of a global note with DTC's custodian, DTC credited portions of the principal amount of the global note to the accounts of the DTC participants designated by the initial purchaser; and



§

ownership of beneficial interests in a global note is shown on, and transfer of ownership of those interests will be effected only through, records maintained by DTC (with respect to interests of DTC participants) and the records of DTC participants (with respect to other owners of beneficial interests in the global note).

Beneficial interests in global notes may not be exchanged for notes in physical, certificated form except in the limited circumstances described below.

Book-Entry Procedures for the Global Notes

All interests in the global notes are subject to the operations and procedures of DTC and, therefore, you must allow for sufficient time in order to comply with these procedures if you wish to exercise any of your rights with respect to the notes. We provide the following summary of those operations and procedures solely for the convenience of investors. The operations and procedures of DTC are controlled by that

Table of Contents

settlement system and may be changed at any time. None of we, the trustee or the initial purchaser are responsible for those operations or procedures.

DTC has advised us that it is:

§

a limited purpose trust company organized under the laws of the State of New York;



§

a "banking organization" within the meaning of the New York State Banking Law;



§

a member of the Federal Reserve System;



§

a "clearing corporation" within the meaning of the Uniform Commercial Code; and



§

a "clearing agency" registered under Section 17A of the Exchange Act.

DTC was created to hold securities for its participants and to facilitate the clearance and settlement of securities transactions between its participants through electronic book-entry changes to the accounts of its participants. DTC's participants include securities brokers and dealers, including the initial purchaser; banks and trust companies; clearing corporations and other organizations. Indirect access to DTC's system is also available to others such as banks, brokers, dealers and trust companies; these indirect participants clear through or maintain a custodial relationship with a DTC participant, either directly or indirectly. Investors who are not DTC participants may beneficially own securities held by or on behalf of DTC only through DTC participants or indirect participants in DTC.

So long as DTC's nominee is the registered owner of a global note, that nominee will be considered the sole owner or holder of the notes represented by that global note for all purposes under the indenture. Except as provided below, owners of beneficial interests in a global note:

§

will not be entitled to have notes represented by the global note registered in their names;



§

will not receive or be entitled to receive physical, certificated notes; and



§

will not be considered the owners or holders of the notes under the indenture for any purpose, including with respect to the giving of any direction, instruction or approval to the trustee under the indenture.

As a result, each investor who owns a beneficial interest in a global note must rely on the procedures of DTC to exercise any rights of a holder of notes under the indenture (and, if the investor is not a participant or an indirect participant in DTC, on the procedures of the DTC participant through which the investor owns its interest). Neither we nor the trustee, paying agent or conversion agent has any responsibility or liability for any act or omission of DTC.

Payments of principal and interest with respect to the notes represented by a global note will be made by the trustee to DTC's nominee as the registered holder of the global note. Neither we nor the trustee will have any responsibility or liability for the payment of amounts to owners of beneficial interests in a global note, for any aspect of the records relating to or payments made on account of those interests by DTC, or for maintaining, supervising or reviewing any records of DTC relating to those interests.

Payments by participants and indirect participants in DTC to the owners of beneficial interests in a global note will be governed by standing instructions and customary industry practice and will be the responsibility of those participants or indirect participants and DTC.

Transfers between participants in DTC will be effected under DTC's procedures and will be settled in same-day funds.

Certificated Notes

Notes in physical, certificated form will be issued and delivered to each person that DTC identifies as a beneficial owner of the related notes only if:

§

DTC notifies us at any time that it is unwilling or unable to continue as depositary for the global notes and a successor depositary is not appointed within 90 days;



§

DTC ceases to be registered as a clearing agency under the Exchange Act and a successor depositary is not appointed within 90 days; or



§

an event of default with respect to the notes has occurred and is continuing and such beneficial owner requests that its notes be issued in physical, certificated form.

DESCRIPTION OF OTHER INDEBTEDNESS

Credit Agreement

On July 16, 2019, we entered into the credit agreement, with Solar, as collateral agent, and the lenders from time to time party thereto (collectively, the "Solar Lenders"). Pursuant to the credit agreement, we borrowed a term loan in an aggregate principal amount of $45.0 million (the "Solar Term Loan"). We used $11.6 million of the Solar Term Loan to repay in full outstanding borrowings under and terminate our then-existing Amended and Restated Loan and Security Agreement.

Interest on the Solar Term Loan is payable monthly at a floating annual rate of 6.50%, plus the greater of (i) the rate per annum rate published by the Intercontinental Exchange Benchmark Administration Ltd. and (ii) 2.48%, provided that the minimum floor interest rate is 8.98%. The maturity date for the Term Loans will be July 1, 2024 (the "Solar Maturity Date"). Commencing on August 1, 2021, we will be required to make monthly principal amortization payments; provided that the interest only period may be extended to (i) August 1, 2022 if our product revenue is greater than or equal to $40.0 million on a trailing six-month basis prior to the second anniversary of the effective date and (ii) August 1, 2023 if our product revenue is greater than or equal to $75.0 million on a trailing six-month basis after the achievement of the first extension.

We may elect to prepay the Solar Term Loan prior to the Solar Maturity Date subject to a prepayment fee equal to 3.00% if the prepayment occurs within one year of the effective date, 2.00% if the prepayment occurs during the second year following the effective date, and 1.00% if the prepayment occurs more than two years after the effective date and prior to the Solar Maturity Date.

The credit agreement contains customary events of default, including bankruptcy, the failure to make payments when due, the occurrence of a material impairment on the Solar Lenders' security interest over the collateral, a material adverse change, the occurrence of a default under certain other agreements entered into by us and our subsidiaries, the rendering of certain types of judgments against us and our subsidiaries, the revocation of certain government approvals, violation of covenants, and incorrectness of representations and warranties in any material respect. Upon the occurrence of an event of default, subject to specified cure periods, all amounts owed by us would begin to bear interest at a rate that is 5.00% above the rate effective immediately before the event of default, and may be declared immediately due and payable by the Solar Lenders.

The Solar Term Loan is secured by substantially all of our and our subsidiaries' assets. The credit agreement also contains specified financial covenants related to our liquidity and trailing six-month revenues. The credit agreement also contains certain restrictive covenants that limit our ability to incur additional indebtedness and liens, merge with other companies or consummate certain changes of control, acquire other companies, engage in new lines of business, make certain investments, pay dividends, transfer or dispose of assets, amend certain material agreements or enter into various specified transactions, as well as financial reporting requirements.

In connection with the closing of the Solar Term Loan, on July 25, 2019 we issued the Solar Lenders warrants to purchase an aggregate of 1,125,000 shares of our common stock with an exercise price of $1.20 per share. The warrants are exercisable until July 25, 2019. The Solar Lenders also have the right to net exercise the warrants for shares of our common stock.

2023 Notes

In January 2018, we issued $50.0 million in aggregate principal amount of 5.25% convertible senior subordinated notes due 2023 (the "2023 notes"), and in February 2018, we issued an additional $3.0 million in aggregate principal amount of 2023 notes. We used $37.9 million of the net proceeds from the issuance of the notes to repurchase $37.0 million aggregate principal amount of 2023 notes, at a

Table of Contents

purchase price equal to the principal amount thereof, plus accrued and unpaid interest thereon. The 2023 notes are general, unsecured, senior subordinated obligations and bear interest at a rate of 5.25% per year, payable semiannually in arrears on February 1 and August 1 of each year, beginning on August 1, 2018. The 2023 notes are not guaranteed and will mature on February 1, 2023, unless earlier repurchased or converted. Payment of the principal of, and accrued and unpaid interest, if any, on the maturity date, and the fundamental change repurchase price of (excluding cash payable in lieu of delivering fractional shares of our common stock), the 2023 notes is subordinated to the prior payment in full in cash or other payment satisfactory to the holders of senior debt, of all existing and future senior debt.

The 2023 notes are convertible into shares of our common stock at the option of the holders at any time prior to the close of business on the business day immediately preceding the maturity date. The conversion rate was initially 294.1176 shares of common stock per $1,000 principal amount of 2023 notes (equivalent to an initial conversion price of approximately $3.40 per share of common stock), subject to customary adjustments. Holders who convert prior to February 1, 2021, may also be entitled to receive, under certain circumstances, an interest make-whole payment payable in shares of our common stock. In addition, following certain corporate events that occur prior to the maturity date, we will, in certain circumstances, increase the conversion rate for a holder who elects to convert its 2023 notes in connection with such a corporate event. As of July 31, 2019, the aggregate outstanding principal amount of the 2023 notes was $15.7 million.

DESCRIPTION OF CAPITAL STOCK

The following description of our capital stock and provisions of our amended and restated certificate of incorporation, our amendment to our amended and restated certificate of incorporation, and amended and restated bylaws are summaries. This description does not purport to be complete and is subject to, and qualified in its entirety by, our amended and restated certificate of incorporation and our amended and restated bylaws, which are incorporated by reference in ourAnnual Report on Form 10-K for the year ended December 31, 2018. The terms of our common stock and preferred stock may also be affected by Delaware law.

Under our amended and restated certificate of incorporation we are authorized to issue up to 450,000,000 shares of common stock, $0.001 par value per share, and 5,000,000 shares of preferred stock, $0.001 par value per share, all of which shares of preferred stock are undesignated. Our board of directors may establish the rights and preferences of the preferred stock from time to time. As of August 6, 2019, we had outstanding 203,168,205 shares of common stock.

Common Stock

Voting Rights

Each holder of our common stock is entitled to one vote for each share on all matters submitted to a vote of the stockholders, including the election of directors. Under our certificate of incorporation and bylaws, our stockholders do not have cumulative voting rights. Because of this, the holders of a majority of the shares of common stock entitled to vote in any election of directors can elect all of the directors standing for election, if they should so choose.

Dividends

Holders of common stock are entitled to receive ratably those dividends, if any, as may be declared from time to time by the board of directors out of legally available funds.

Liquidation

In the event of our liquidation, dissolution or winding up, holders of common stock will be entitled to share ratably in the net assets legally available for distribution to stockholders.

Rights and Preferences

Holders of common stock have no preemptive, conversion or subscription rights and there are no redemption or sinking fund provisions applicable to the common stock. The rights, preferences and privileges of the holders of common stock are subject to, and may be adversely affected by, the rights of the holders of shares of any series of preferred stock that we may designate in the future.

Registration Rights

We and certain holders of our common stock have entered into a registration rights agreement (the "existing registration rights agreement"). The registration rights provisions of that agreement provide those holders with demand, piggyback and Form S-3 registration rights. The shares subject to such rights are referred to herein as "Registrable Shares."

In addition, pursuant to the terms of certain of our warrants to purchase common stock held by Oxford, Oxford has piggyback registration rights with respect to the shares of common stock issuable upon the exercise of the warrants on the same terms as are set forth in the existing registration rights agreement.

Demand Registration Rights

The holders of at least a majority of the Registrable Shares in the aggregate, or a lesser percent if the anticipated aggregate offering price would exceed $10.0 million, have the right to demand that we filed up to a total of two registration statements. These registration rights are subject to specified conditions and limitations, including the right of a managing underwriter to limit the number of shares included in any

Table of Contents

such registration under specified circumstances. Upon such a request, we are required to effect the registration as expeditiously as possible.

Piggyback Registration Rights

If we propose to register any of our securities under the Securities Act of 1933, as amended, either for our own account or for the account of other stockholders, the holders of Registrable Shares and Oxford will each be entitled to notice of the registration and will be entitled to include their shares of common stock in the registration statement. These piggyback registration rights are subject to specified conditions and limitations, including the right of a managing underwriter to limit the number of shares included in any such registration under specified circumstances. The requisite holders of piggyback registration rights under our existing registration rights agreement have waived these rights as they may apply to the filing of this registration statement.

Registration on Form S-3

If we are eligible to file a registration statement on Form S-3, the holders of Registrable Shares will be entitled, upon their written request, to have such shares registered by us on a Form S-3 registration statement at our expense, provided that such requested registration has an anticipated aggregate offering size to the public of at least $1.0 million and subject to other specified conditions and limitations.

Expenses of Registration

We will pay all expenses relating to any demand, piggyback or Form S-3 registration, other than underwriting discounts and commissions, subject to specified conditions and limitations.

Termination of Registration Rights

The registration rights granted under the existing registration rights agreement will terminate on August 4, 2025 or, if earlier, with respect to a particular holder, at such time as that holder and its affiliates may sell all of their shares of common stock pursuant to Rule 144 under the Securities Act without any restrictions on volume.

Warrants

As of August 6, 2019, we had outstanding warrants to purchase an aggregate of 116,581, 63,025, 80,645 and 1,125,000 shares of common stock at an exercise price of $3.86, $2.38, $1.86 and $1.20 per share, respectively. These warrants expire on June 30, 2026, November 22, 2026, March 29, 2027 and July 25 2029, respectively. We also had outstanding warrants to purchase 167,570 shares of common stock at an exercise price of $1.79 per share, which warrants expire on November 2, 2020, July 14, 2021, and August 19, 2021. The number of shares of common stock issuable upon the exercise of each warrant is subject to adjustment from time to time upon the occurrence of specified events.

Preferred Stock

Pursuant to our amended and restated certificate of incorporation (the "Restated Certificate"), our board of directors has the authority, without further action by the stockholders (unless such stockholder action is required by applicable law or stock exchange listing rules), to designate and issue up to 5,000,000 shares of preferred stock in one or more series, to establish from time to time the number of shares to be included in each such series, to fix the designations, powers, preferences, privileges and relative participating, optional or special rights and the qualifications, limitations or restrictions thereof, including dividend rights, conversion rights, voting rights, terms of redemption and liquidation preferences, any or all of which may be greater than the rights of the common stock, and to increase or decrease the number of shares of any such series, but not below the number of shares of such series then outstanding.

The board of directors, without stockholder approval, can issue preferred stock with voting, conversion or other rights that could adversely affect the voting power and other rights of the holders of common stock. Preferred stock could be issued quickly with terms designed to delay or prevent a change in control of our company or make removal of management more difficult. Additionally, the issuance of preferred stock may

Table of Contents

have the effect of decreasing the market price of the common stock and may adversely affect the voting power of holders of common stock and reduce the likelihood that common stockholders will receive dividend payments and payments upon liquidation.

Our board of directors will fix the designations, voting powers, preferences and rights of the each series, as well as the qualifications, limitations or restrictions thereof, of the preferred stock of each series in the certificate of designation relating to that series. We will file as an exhibit to a registration statement, or will incorporate by reference from reports that we file with the SEC, the form of any certificate of designation that describes the terms of the series of preferred stock we are offering before the issuance of that series of preferred stock. This description will include:

§

the title and stated value;



§

the number of shares we are offering;



§

the liquidation preference per share;



§

the purchase price per share;



§

the dividend rate per share, dividend period and payment dates and method of calculation for dividends;



§

whether dividends will be cumulative or non-cumulative and, if cumulative, the date from which dividends will accumulate;



§

our right, if any, to defer payment of dividends and the maximum length of any such deferral period;



§

the procedures for any auction and remarketing, if any;



§

the provisions for a sinking fund, if any;



§

the provisions for redemption or repurchase, if applicable, and any restrictions on our ability to exercise those redemption and repurchase rights;



§

any listing of the preferred stock on any securities exchange or market;



§

whether the preferred stock will be convertible into our common stock or other securities of ours, including depositary shares and warrants, and, if applicable, the conversion period, the conversion price, or how it will be calculated, and under what circumstances it may be adjusted;



§

whether the preferred stock will be exchangeable into debt securities, and, if applicable, the exchange period, the exchange price, or how it will be calculated, and under what circumstances it may be adjusted;



§

voting rights, if any, of the preferred stock;



§

preemption rights, if any;



§

restrictions on transfer, sale or other assignment, if any;



§

whether interests in the preferred stock will be represented by depositary shares;



§

a discussion of any material or special United States federal income tax considerations applicable to the preferred stock;



§

the relative ranking and preferences of the preferred stock as to dividend rights and rights if we liquidate, dissolve or wind up our affairs;



§

any limitations on issuances of any class or series of preferred stock ranking senior to or on a parity with the series of preferred stock being issued as to dividend rights and rights if we liquidate, dissolve or wind up our affairs; and



§

any other specific terms, rights, preferences, privileges, qualifications or restrictions of the preferred stock.

The General Corporation Law of the State of Delaware (the "DGCL"), the state of our incorporation, provides that the holders of preferred stock will have the right to vote separately as a class (or, in some cases, as a series) on an amendment to our certificate of incorporation if the amendment would change the par value or, unless the certificate of incorporation provided otherwise, the number of authorized shares of the class

Table of Contents

or change the powers, preferences or special rights of the class or series so as to adversely affect the class or series, as the case may be. This right is in addition to any voting rights that may be provided for in the applicable certificate of designation.

Antitakeover Effects of Provisions of Charter Documents and Delaware Law

Charter Documents.    Our Restated Certificate and Amended and Restated Bylaws (our "Bylaws"), each as amended to date, include a number of provisions that may have the effect of deterring hostile takeovers or delaying or preventing changes in control or management of our company. First, our board of directors is classified into three classes of directors. Under Delaware law, directors of a corporation with a classified board may be removed only for cause unless the corporation's certificate of incorporation provides otherwise. Our Restated Certificate does not provide otherwise. In addition, the Restated Certificate provides that all stockholder action must be effected at a duly called meeting of stockholders and not by a consent in writing. Further, our Bylaws limit who may call special meetings of the stockholders. Our Restated Certificate does not include a provision for cumulative voting for directors. Under cumulative voting, a minority stockholder holding a sufficient percentage of a class of shares may be able to ensure the election of one or more directors. Finally, our Bylaws establish procedures, including advance notice procedures, with regard to the nomination of candidates for election as directors and stockholder proposals. These and other provisions of our Restated Certificate and Bylaws and Delaware law could discourage potential acquisition proposals and could delay or prevent a change in control or management of our company.

Delaware Takeover Statute.    We are subject to Section 203 of the DGCL, which regulates acquisitions of some Delaware corporations. Section 203 generally prohibits a publicly held Delaware corporation from engaging in a "business combination" with an "interested stockholder" for a period of three years following the date of the transaction in which the person became an interested stockholder, unless:

§

the board of directors of the corporation approved the business combination or the other transaction in which the person became an interested stockholder prior to the date of the business combination or other transaction;



§

upon consummation of the transaction that resulted in the person becoming an interested stockholder, the person owned at least 85% of the voting stock of the corporation outstanding at the time the transaction commenced, excluding shares owned by persons who are directors and also officers of the corporation and shares issued under employee stock plans under which employee participants do not have the right to determine confidentially whether shares held subject to the plan will be tendered in a tender or exchange offer; or



§

on or subsequent to the date the person became an interested stockholder, the board of directors of the corporation approved the business combination and the stockholders of the corporation authorized the business combination at an annual or special meeting of stockholders by the affirmative vote of at least 66²/3% of the outstanding stock of the corporation not owned by the interested stockholder.

Section 203 of the DGCL defines a "business combination" to include any of the following:

§

any merger or consolidation involving the corporation and the interested stockholder;



§

any sale, transfer, pledge or other disposition of 10% or more of the corporation's assets or outstanding stock involving the interested stockholder;



§

subject to exceptions, any transaction that results in the issuance or transfer by the corporation of any of its stock to the interested stockholder;



§

any transaction involving the corporation that has the effect of increasing the proportionate share of its stock owned by the interested stockholder; or



§

the receipt by the interested stockholder of the benefit of any loans, advances, guarantees, pledges or other financial benefits provided by or through the corporation.

Table of Contents

In general, Section 203 defines an "interested stockholder" as any person who, together with the person's affiliates and associates, owns, or within three years prior to the determination of interested stockholder status did own, 15% or more of a corporation's voting stock.

Section 203 of the DGCL could depress our stock price and delay, discourage or prohibit transactions not approved in advance by our board of directors, such as takeover attempts that might otherwise involve the payment to our stockholders of a premium over the market price of our common stock.

Transfer Agent And Registrar

The transfer agent and registrar for our common stock is Computershare Trust Company, N.A., and its address is 250 Royall Street, Canton, Massachusetts 02021.
